Question

(w-10x) (w+10x) Use the Identities to solve this question

Answer 1

We are provided that –

• (w-10x) (w+10x)

Applying identity –

• a² - b² = (a + b)(a - b)

$\qquad$ $\twoheadrightarrow\bf(w-10x) (w+10x)$

$\qquad$ $\twoheadrightarrow\bf w^2 - (10x)^2$

$\qquad$ $\twoheadrightarrow\bf w^2 -100 x^2$
