Question

What is the standard form of `y=(2x+5)(2x-3) -3x^2+6x`?

Answer 1

#x^2+10x-15

Explanation:

The standard form of an equation such as this is: `ax^2 + bx + c`

By expanding and simplifying the question, we can get the answer:
`y = (2x+5)(2x-3) - 3x^2 + 6x`
`=4x^2-6x+10x-15-3x^2+6x`
`=x^2+10x-15`
