How do you multiply (3x-7)(5x+6)?

Dana Sanford

Explanation:
(3x-7)(5x+6)
So we need to use the FOIL method to see what this will give us.
$15{x}^{2}+18x-35x-42$
So once you are finish using the FOIL method, combine the like terms. The final answer to this is:
$15{x}^{2}-17x-42$

To multiply the two binomials (3x-7)(5x+6)
We use the mnemonic FOIL
F - First terms $\left(3x\right)\left(5x\right)=15{x}^{2}$
O - Outer terms (3x)(6)=18x
I - Inner terms (-7)(5x)=-35x
L - Last terms (-7)(6)=-42
Now combine the terms
$15{x}^{2}+18x-35x-42$
$15{x}^{2}-17x-42$
