Question

Factorise the following
49 x² - 36​

Answer 1

Answer:

The given algebraic expression, a quadratic binomial, 49x² - 36 = 7x² - 6² , falls into the pattern of the "Difference of Two Squares": a² - b² = (a + b)(a - b), where, in this case, a = 7x and b = 6. x² - 7² = (7x + 6)(7x - 6) is the original algebraic expression, 49x² - 36, factored.

Hope it helps........
