$y=4x^2+18x+14$

Write as $y=color(blue)((2x+7))color(brown)((2x+2))$

Multiply everything in the right hand side brackets by everything in the left. Note that the + in +7 follows the 7.

$y=color(brown)(color(blue)(2x)(2x+2)" "color(blue)(+7)(2x+2))$

$y=4x^2+4x" "+14x+14$

$y=4x^2+18x+14$

What is the standard form of y= (2x + 7) (2x + 2) y= (2x + 7) (2x + 2) ?
