You must use the "*" (star) symbol for all multiplications!x(x+1) is WRONG! It means a function x of x-1.x*(x-1) is right.Use the ^ (caret) for exponentiation. x^2 means x squared. x/2y means Resources: Simplifier Portal, help with entering simplifier formulas (a must read).Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.mom above was the only one who got this right. First you multiply it out: 3(x+1)(x+1)-12. 3(x^2+2x+1)-12. 3x^2+6x+3-12... now combine like terms: 3x^2+6x-9(x+(1/2)) • (x+(1/2)) = (x+(1/2)) 2 Things which are equal to the same thing are also equal to one another. Since x 2 +x+(1/4) = -3/4 and x 2 +x+(1/4) = (x+(1/2)) 2 then, according to the law of transitivity, (x+(1/2)) 2 = -3/4 We'll refer to this Equation as Eq. #2.2.1Free functions calculator - explore function domain, range, intercepts, extreme points and asymptotes step-by-step!
Simplify 1/2x^(-1/2) | Mathway
Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.All equations of the form ax^{2}+bx+c=0 can be solved using the quadratic formula: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.Divide \frac{4}{3}, the coefficient of the x term, by 2 to get \frac{2}{3}. Then add the square of \frac{2}{3} to both sides of the equation. This step makes the left hand side of the equation a perfect square.(x+(1/2)) • (x+(1/2)) = (x+(1/2)) 2 Things which are equal to the same thing are also equal to one another. Since x 2 +x+(1/4) = 289/4 and x 2 +x+(1/4) = (x+(1/2)) 2 then, according to the law of transitivity, (x+(1/2)) 2 = 289/4 We'll refer to this Equation as Eq. #4.2.1
How do you factor 3(x+1)^2 - 12? | Yahoo Answers
common denominator is (x+1)^2: x^2 + x^2 / (x+1)^2 = 3. x^2(x+1)^2/(x+1)^2 + x^2/(x+1)^2 = 3(x+1)^2/(x+1)^2. SINCE ENTIRE EQUATION IS OVER (x+1)^2, drop denomiantors and solve using numerators:Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.Using Power Rules and Simple maths [math]4^x - 3^{x-\frac{1}{2}} = 3^{x+\frac{1}{2}} - 2^{2x-1} \\[/math] [math]2^{2x} + 2^{2x-1} = 3^{x+\frac{1}{2}} + 3^{x-\frac{1Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-stepProve that { 1 , 1 + x , (1 + x)^2 } is a basis for the vector space of polynomials of degree 2 or less. Then express f(x) = 2 + 3x - x^2 as a linear combination.
(*1*) This equation is in usual shape: ax^2+bx+c=0. Substitute 1 for a, -2 for b, and 3-y for c in the quadratic components, \frac-b±\sqrtb^2-4ac2a.
This equation is in usual shape: ax2+bx+c=0. Substitute 1 for a, −2 for b, and three−y for c within the quadratic method, 2a−b±b2−4ac.
