Answer 1

you have to distribute. i think the answer is 10x^4+65X^3-25X^2

Answer 2

Answer:

$10x^4+65x^3-25x^2$

Step-by-step explanation:

Multiply 5x^2(2x^2 + 13x − 5)

$5x^2(2x^2 + 13x - 5)$

Multiply 5x^2 inside the parenthesis

$5x^2 * 2x^2 = 10x^4$

$5x^2 * 13x = 65x^3$

$5x^2 * (-5) = -25x^2$

Collect all the terms together

$10x^4+65x^3-25x^2$
