Question

simplify 7x(2x+y)-(4x-Y)^2

Answer 1

First, distribute 7x on the left parentheses and square the right binomial.

Answer 2

I am assuming this is what you mean:
\(7x(2x + y) - (4x - y)^2\)

Answer 3

\[7x(2x+y) - (4x- y)^{2}\]
\[(14x^2+7xy) - (16x^2- y^2 -8xy)\]
now solve the brackets

Answer 4

@sangya21
You wrote this: \((14x^2+7xy) - (16x^2- y^2 -8xy)\)
but I'm sure you meant this: \(\large(14x^2+7xy) - (16x^2\color{red}{+} y^2 -8xy)\)

Answer 5

That's correct. I apologize for the mistake
