Simplify the product (x-4)(x+3)
Kamila [148]

Answer:

Final answer is x^2-x-12.

Step-by-step explanation:

Given expression is \left(x-4\right)\left(x+3\right).

Now we need to find the product of the given expression \left(x-4\right)\left(x+3\right).

\left(x-4\right)\left(x+3\right)

=x\left(x-4\right)+3\left(x-4\right)

=x^2-4x+3x-12

combine like terms

=x^2-1x-12

=x^2-x-12

Hence final answer is x^2-x-12.
