Answer:
(a + 2)
Step-by-step explanation:
To factor the quadratic, consider the factors of the constant term which sum to give the coefficient of the a term, that is
factors which multiply to give + 10 and sum to + 7
the required factors are + 5 and + 2, hence
a² + 7a + 10 = (a + 5)(a + 2)
Answer:
Step-by-step explanation:
90(n-98)²=90(97-98)²=90(-1)²=90*1=90
