Question

Simplify the expression (2x − 9)(x + 6)

Answer 1

do you know how to foil?

Answer 2

please, you have to apply the distributive property of multiplication over algebraic sum!

Answer 3

I think the foil method would be best in this case. Foil stands for First Outer Inner Last.
So you would take the first numbers in the equation and multiply.
\[2x \times x= 2x ^{2}\]
the outer and inner steps go together.
You multiply the outer numbers first: \[2x \times 6 = 12x\]
Then, the inner numbers: \[-9 \times x =-9x\]
Then you would add both of the products: \[12x - 9x = 3x\]
Now, you will multiply the last numbers.
\[-9 \times 6 =-54\]

So your answer will be:
\[2x ^{2}+3x -54\]
