Question

how to solve this eqution?

$100 - 9 {p}^{2}$

Answer 1

To factorise the given polynomial, try to convert the given polynomial where you can apply any identity.

Solution.)

100 - 9p^2

=> (10)^2 - (3p)^2

Here, use the identity [ a^2 - b^2 = (a+ b) (a-b)]

=> ( 10 + 3p) (10 - 3p)

Answer 2

Hy
Here is your answer
===================
100 - 9p²

=> (10)² - (3p))²

Here, use the identity [ a² - b² = (a+ b) (a-b)]

=> ( 10 + 3p) (10 - 3p)
