Question

(2ax + 1/2 bx)2

Answer 1

(2ax+1/2bx)(2ax+1/2bx)

(2ax)(2ax)= 4a^2x^2
(2ax)(1/2bx)=abx^2
(1/2bx)(2ax)=abx^2
(1/2bx)(1/2bx)=0.25b^2x^2

\[4a^{2}x ^{2}+2abx ^{2}+0.25b ^{2}x ^{2}\]

Answer 2

if you have \[\left( 2ax+ \frac{1}{2}bx \right)^2\]then the expansion is\[=4a^2x^2+2abx^2+\frac{1}{4}b^2x^2\]

Answer 3
