Question

find the value of
(8a+3b)^2​

Answer 1

Question -

$(8a+3b)^{2}$

Step-by-step explanation:

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

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

using this formula in the above question we get

$(8a+3b)^{2} = (8a)^{2} + 2(8a)(3b) + (3b)^{2}$

$(8a+3b)^{2} = 64a^{2} + 48ab + 9b^{2}$
