Question

factorise the following expression 100-9p^2​

Answer 1

Step-by-step explanation:

100 - 9p²

=(10)² - {(3)p}²

[Now, from formula (a²-b²) = (a+b)(a-b)]

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

Hence, solved

Answer 2

100-9p^2

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

Now, this is in a^2 - b^2 format

a^2-b^2 = (a+b) (a-b)

So, (10)^2 - (3p)^2

= (10+3p)(10-39)
