Answer:
x² -7x -18
Step-by-step explanation:
In algebra, a binomial consists solely of a sum or subtraction of two monomials.
To solve the multiplication of two binomials we have to multiply term by term and then simplify common terms.
(x + 2)(x - 9) = x(x) + x(-9) +2(x) + 2(-9) = x² -9x + 2x -18 = x² -7x - 18
Answer:
-22
Step-by-step explanation:
Due to order of operations rules, we must perform the subtraction inside parentheses first, getting:
-4 +(3)(-6)
Multiplication comes next:
-4 - 18
and the total value is thus -22.
