Question

20(p²-q²)² - 30(p²-q²)³ + 5(p²-q²)​

Answer 1

= 20(p^2-q^2)^2-30(p,^2-q^2)^3+5(p^2-q^2)

= -10(p^2-q^2)^3 + 5(p^2-q^2)

= -5^3

Answer 2

Following are the steps for getting the answer:

Given:

20(p²-q²)² - 30(p²-q²)³ + 5(p²-q²)​

To find:

20(p²-q²)² - 30(p²-q²)³ + 5(p²-q²)​=?

Solution:

we have to simplify the given expression

so first we will expand the expression

$= 20(p^2-q^2)^2-30(p,^2-q^2)^3+5(p^2-q^2)\\\\= -10(p^2-q^2)^3 + 5(p^2-q^2)\\\\= -5^3$

By simplifying the expression we get -5³

-5³=-125

Thus, the answer of 20(p²-q²)² - 30(p²-q²)³ + 5(p²-q²)​ is -5³ or -125
