Multiply:
(x-5)(x+9)

x² + 4x - 45

Step-by-step explanation:

We can use the FOIL (First, Outer, Inner, Last) method to multiply the two binomials.

First: Multiply  the first components of the binomials.

Outer: Multiply the first component of the first binomial with the last component of the second binomial.

Inner: Multiply the last component of the first binomial with the first component of the second binomial.

Last: Multiply the last components of the binomials.

(x · x) + (x · 9) + (-5 · x) + (-5 + 9) = x² + 9x - 5x - 45 = x² + 4x - 45

(x-5)(x+9) = x² + 4x - 45

I hope this helps. :)
