Question

The binomial (a+5) is a factor of a2+7a+10. What is the other factor? (a+2) (a+5) (a−2) (a−5)The binomial (y − 2) is a factor of y2 − 10y + 16. What is the other factor? (y − 5) (y + 5) (y − 8) (y + 8)

Answer 1

Explanation:

a^2 +7a + 10 = a(a+2) +5(a+2) = (a+5)(a+2)

y^2 -10y +16=y(y-2) -8(y-2) =(y-8)(y-2)
