hope it helps u

Answer 2

Answer:

We can answer this using identities

Step-by-step explanation:

The  identity is $(a + b)(a - b) = a^2 - b^2$

(a) By substituting. We get,

$25p^2 - 36q^2 = (a + b)(a - b)\\\= \sqrt{25p^2} - \sqrt{36q^2}\\= (5p)^2 - (6q)^2\\= (5p + 6q)(5p - 6q)$

So, the answer is $(5p + 6q)(5p - 6q)$

(b) By using the same identity. We get,

$x^2 - 49 = (a + b)(a - b)\\= \sqrt{x^2} - \sqrt{49} \\= (x)^2 - (7)^2\\= (x + 7)(x - 7)$

So, the answer is $(x + 7)(x - 7)$
