Question

What is the standard form of # y= (5x+2)^2 + 11(5x+2)+30 #?

Answer 1

Standard form of a quadratic is `ax^2 + bx+ c`

Explanation:

This expression can be considered as being in standard form already, if you let `(5x + 2) = m`

It then becomes `y = m^2 + 11m + 30`

However, if you multiply out and simplify it becomes:

`y = 25x^2 + 75x+ 56`
