Answer:

x² + 2x - 3

Step-by-step explanation:

Given

(x + 3)(x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 1) + 3(x - 1) ← distribute both parenthesis

x² - x + 3x - 3 ← collect like terms

= x² + 2x - 3

Answer:

x^2+2x−3

Step-by-step explanation:

lets use the multiplication property of distrubution.

x * x = x^2

x * -1 = -x

(x+3)(x−1)

=(x+3)(x+−1)

=(x)(x)+(x)(−1)+(3)(x)+(3)(−1)

=x2−x+3x−3

=x^2+2x−3
