< B.5 14. Multiply & simplify: (3x + 4)(x + 1)

Step-by-step explanation:

Using FOIL (First, outer, inner, last)

First, we multiply 3x and x to get (First)

We then multiply 3x and 1 to get (outer)

Then 4 and x to get (Inner)

Then multiply 1 and 4 to get (last)

Since the quadratics are all positive, we add all the terms together to get:

. Since 3x and 4x are like terms, we add them together and simplify to get:

And since we can't simplify any further, that's our answer!

Hope this helps :D

Step-by-step explanation:

To simplify the double bracket, you can use a Foil method ( you can search it to see detailed explanation )

(3x + 4 )( x + 1)

Hope that is right, ask any questions if unsure :)

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
