Question

4x(x+2)+3.2x(x-2)=5.2x(x+2)

Answer 1

4x(x+2)+3*2x(x-2)=5*2x(x+2)

=>\(4x\left(x+2\right)+6x\left(x-2\right)-10x\left(x+2\right)=0\)

=>\(-6x\left(x+2\right)+6x\left(x-2\right)=0\)

=>-x(x+2)+x(x-2)=0

=>-x(x+2-x+2)=0

=>-x=0

=>x=0

Answer 2

\(4x\left(x+2\right)+3\cdot2x\left(x-2\right)=5\cdot2x\left(x+2\right)\)

\(4x^2+8x+6x^2-12x=10x^2+20x\)

\(10x^2-4x=10x^2+20x\)

\(10x^2-4x-10x^2-20x=0\)

\(-24x=0\Rightarrow x=0\)
