Question

(8x + 3y)^2 = (a+b)^2= a^2+2ab+b^2
​

Answer 1

Answer:

$\boxed{(8x+3y)^2=64x^2+48xy+9y^2}$

Step-by-step explanation:

$proper \: quesion$

expand $\underline{8x+3y)^2}$

by using the identity $\underline{(a+b)^2}$

$\boxed{Answer}$

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

now using the above identity

we get

$(8x + 3y) { }^{2} =(8x) {}^{2} + 2(8x)(3y) + (3y) {}^{2}$

$(8x + 3y) {}^{2} = 64x {}^{2} + 48xy + 9y {}^{2}$
