<span>x^2+7x-18

Ask yourself: 
What adds up to 7 but multiplies to -18? 

In this case: 
9 and -2 would be the answer. 

9 * -2=-18
9-2=7 

Factor form: 
(x-2)(x+9) 

Final answer: 
(x-2)(x+9)</span>

What is 3x + 2 + 4x - 1 after combining like terms
ivanzaharov [21]

Answer:

7x+1

Step-by-step explanation:

When you look at the expression(3x+2+4x-1), you will notice that some have variables while some are just regular numbers.

First, focus on the variables. 3x and +4x. In the expression, you will have to add it so 3x+4x will be 7x. Now, keep 7x on the side and switch to the numbers.

Next, focus on the numbers. 2 and -1. All you have to do is combine them which will be 2-1 which also equals 1.

Finally, return 7x with 1 which will be 7x+1. The reason you add a + sign instead of a - sign is because you got positive 1, not negative 1.

Your answer is 7x+1.
