Question

Simplify 2.5*(x+0.6)^2 = 3.5x^2

Answer 1

\[2.5*(x+0.6)^2 = 3.5x^2\]

Answer 2

do you know the laws of the indices

Answer 3

Thus far I've simplified it to \[(x+0.6)^2=1.4x^2\] however, I'm not sure whether I should square root at this point. I do know the laws of the indices so I know I can't distribute the square over the parenthesis.

Answer 4

expand the left hand side

Answer 5

\[x^2+1.2x+.36=1.4x^2\] then solve a quadratic equation,
