Question

find the product of (3a+10) (3a+4) using suitable identities​

Answer 1

Answer:

Use the formula (x + a) (x + b) = x2 + x(a + b) + ab to identity to find the following products. ...Use the formula (x + a) (x - b) = x2 + x (a – b) – ab to identity to find the following products

Answer 2

Answer:

9a^2+42a+40

Here we used the identity

$(x + a)(x + b) = {x}^{2} + x(a + b) + ab$

Hope this answer helps you.
