Question

Answer this by expanding the brackets 20 POINTS!

Answer 1

Answer:

Below

Step-by-step explanation:

(y - 9)(y - 7) = $y^2-16y+63$

(2y + 2)(y + 1) = $2y^2+4y+2$

(2y + 6)(y + 3) =  $2y^2+12y+18$

(3y + 4)(y + 5) = $3y^2+19y+20$

(2y - 7)(y + 2) = $2y^2-3y-14$

Answer 2

Answer:

$\huge \boxed{y^2 - 16y + 63}$

$\rule[225]{225}{2}$

Step-by-step explanation:

Solving for the first problem:

(y-9)(y-7)

y(y-7)-9(y-7)

y² - 7y - 9y + 63

y² - 16y + 63

$\rule[225]{225}{2}$
