Question 122700: a^2 +3a - 10
Answer by apachemexican1(64) (Show Source): You can put this solution on YOUR website!
step 1: note that x^2= x*x
step 2: factor the constant term.
since the coefficient of the middle
x term is +3, choose the factors
-2 and 5, which combine to +3.
-10=(-1)(10) or (1)(-10)
or (-2)(5) or (2)(-5)
step 3: write the answer using parenthesis
beginning with x followed by the
numerical factors
(x-2)(x+5)
to check your answer, you can use
the FOIL method to multiply the factors
(x-2)(x+5)=x^2+3x-10
