Rewrite the expression 7x^2 + 7x - 42 as THREE factors where one of the factors is an integer value.

<h3>Answer:  7(x+3)(x-2)</h3>

========================================

Explanation:

First factor out the GCF 7

7x^2 + 7x - 42

7*x^2 + 7*x + 7*(-6)

7(x^2 + x - 6)

Now focus on factoring x^2+x-6

We need to find two numbers that multiply to -6 and add to 1. Those values are 3 and -2. That means x^2+x-6 factors to (x+3)(x-2).

The 7(x^2 + x - 6) then turns into 7(x+3)(x-2)

The factor out front, the "7", is the integer factor. The other factors (x+3) and (x-2) are binomial factors.

Lexi, susie and rial are playing an online word game. Rial scores 100,034 points. Lexi scores 9,348 fewer points than rial and s
Troyanec [42]
To solve this problem, you first need to subtract 100,034-9,348. You do this because Lexi scored that many points LOWER than Rial.  You then take the answer to that subtraction problem (90,696) and add 9,749 to that answer. You do this because Susie scored 9,749 MORE than Lexi. You should get 100,435. This is Susie's score, so your final answer is 100,435 points.

A: -4<br> B: -16<br> C: 15<br> D: -5
baherus [9]
The answer here is B. -16

10 + -16 equals -6 and a negative divided by a negative is a positive so -6 divided by -3 is -2.

Hope this helps!
