Question

(3p - 4q)^2 is equals to​

Answer 1

Answer:

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

Step-by-step explanation:

( 3p-4q)^2 = (3p)^2 - 2 * 3p * 4q - (4q)^2

               = 9p^2 -24pq - 16q^2

Answer 2

Question :-

Solve

(3p - 4q)²

Answer:-

9p² - 24pq + 16q²

By using formula:-

(a - b)² = a² - 2ab + b²

Solution:-

= (3p)² - 2×3p×4q + (4q)²

= 9p² - 24pq + 16q²

= 9p² - 24pq + 16q²

More to know :-

• (a + b)² = a² + 2ab + b²

• (a - b)² = a² - 2ab + b²

• (a + b)(a - b) = a² - b²

• (x + a)(x + b) = x² + x(a + b) + ab
