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
