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

Question

anonymous · Answer

do you know how to foil?

michele_laino · Answer

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

anonymous · Answer

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:
$$2x ^{2}+3x -54$$

Hope this helps! :)
