$y=x^2+7x+10$

given: $" "y=color(blue)((x+5)color(green)((x+2))$

Multiply everything inside the right bracket by everything inside the left.

$color(green)(y=color(blue)(x)(x+2)" "color(blue)(+" "5)(x+2))$

$y=x^2+2x" "+" "5x+10$

$y=x^2+7x+10$

How do you write the function in standard form y=(x+5)(x+2)y=(x+5)(x+2)?
