Question

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

Answer 1

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

Explanation:

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`
