Question

What is the product of x-3 and 4+x​

Answer 1

Answer:

x2+11x+28

Step-by-step explanation:

We have two binomials, so we can use the highly useful mnemonic FOIL to helps us:

Multiply the first terms:  

x

⋅

x

=

x

2

Multiply the outside terms:  

x

⋅

4

=

4

x

Multiply the inside terms:  

7

⋅

x

=

7

x

Multiply the last terms:  

7

⋅

4

=

28

Thus,  

(

x

+

7

)

(

x

+

4

)

multiplies out to  

x

2

+

4

x

+

7

x

+

28

, which can be simplified to:

x 2 +11 x + 28

Hope this helps!
