How do you factor 9x 2 -1
WebTo verify that our answer is correct, we can calculate the product of the factors to see if it equals 9x^2+1. And it does, as illustrated below: = (3x + 1i) • (3x − 1i) = 3x (3x - 1i) + 3x (3x - 1i) = 9x 2 - 3xi + 3xi - 1i 2 - 3xi + 3xi evens out and -i 2 equals -1, so now we get this: = 9x 2 - 1 (-1) = 9x 2 + 1 Factoring Sum of Squares WebHow do you factor 9x^2 + 9x -4? 9x^2 + 9x - 4 → 9* (-4) = - 36 = 12* (-3) → 12 + (-3) = 9 For ax^2 + bx + c, take a*c and factor it so that the factors add to b, then rewrite the middle term as two terms using the factors of a*c that you found. Factor by grouping 9x^2 + 9x - 4 = 9x^2 - 3x + 12x - 4 = 3x (3x - 1) + 4 (3x - 1) = (3x - 1) (3x + 4)

Algebra Polynomials and Factoring Factorization of Quadratic Expressions 1 Answer EZ as pi Jun 28, 2024 (3x +4)(3x + 4) Explanation: Find factors of 9 and 16 whose products add to 24 Note that both 9 and 16 are squares . 3 × 4 = 12, and 12 +12 = 24 9x2 + 24x +16 = (3x + 4)(3x + 4) Answer link WebMultiply the number and variable together to get 2x. Then divide each part of the expression by 2x. 2x ^3 / 2x = x^ 2 18x ^2 / 2x = 9x 10x / 2x = 5 The expression with the GCF factored out is 2x (x^ 2 + 9x + 5). Note that you must put the factored expression in parentheses and write the GCF next to it. Add Tip Ask Question Comment Download
