Respuesta :

(y-3)(y+10)

mutiply the two brackets together

(y)(y)= y^2

(y)(10)= 10y

(-3)(y)= -3y

(-3)(10)= -30

y^2+10y-3y-30

Answer: y^2+7y-30

Answer:

y^2 +7y-30

Step-by-step explanation:

Step 1:  Use FOIL

y·y = y^2

y· 10= 10y

-3·y= -3y

-3·10= -30

Step 2: combine like terms

y^2+ 10y-3y-30

7^2+ 7y-30

and thats all :)

hope this helped
