Question

Can someone help me solve this?

What is the product of these binomials?

(x + 6)(x + 3) =

Answer 1

\[x^{2} + 9x + 18\]

Answer 2

So was I supposed to add the multiply 3 and 8?

Answer 3

I mean 3 and 6?

Answer 4

\[x ^{2}+ 3x + 6x + 18 \]

Answer 5

thats what i got when i multiplied it out then i added the 3x and 6x

Answer 6

You use the FOIL method to solve this.

FOIL stands for First,Outside,Inside,Last and refers to the positions of the terms in the binomials.

IOW, for "(x + 6)(x + 3)", you would:

Multiply the (F)irst terms first:

x*x = x^2

Then multiply the (O)utside terms:

x*+3 = +3x

Then multiply the (I)nside terms

+6*x = +6x

And finally you multiply the last terms:

+6 * +3= +18

Now you string these products all together and you get:

X^2 +3x +6x +18

Now combine common terms and you're done:

X^2 +9x +18
