Question

Which expression is equivalent to (x2 - 2x)(3x2 + 4x - 7)? A. 7(3x2 + 4x - 7) – 2*13x + 4x - 7) B. x(3x2 + 4x - 7) - 2x C. X(3y2 + 4x - 7) + 2x(3x2 + 4x-7) D. (3x2 + 4x) - 2x{4x - 7)

Answer 1

Given the equation:

$(x^2-2x)(3x^2+4x-7)$

To find the the equivalent expression, Let's simplify:

Expand using distributive property.

$\begin{gathered} (x^2-2x)(3x^2+4x-7) \\ \\ x^2(3x^2+4x-7)-2x(3x^2+4x-7) \\ \\ \end{gathered}$

ANSWER:

$x^2(3x^2+4x-7)-2x(3x^2+4x-7)$
