Step-by-step explanation:
5x can also be written as " -3x + 8x " so:
![x^2+5x-24 = x^2-3x+8x-24](https://tex.z-dn.net/?f=x%5E2%2B5x-24%20%3D%20x%5E2-3x%2B8x-24)
Using the distributive property:
![x(x-3)+8(x-3)](https://tex.z-dn.net/?f=x%28x-3%29%2B8%28x-3%29)
Then again, using the distributive property (but in reverse):
![(x-3)(x+8)](https://tex.z-dn.net/?f=%28x-3%29%28x%2B8%29)
The two numbers that the middle term should be split into in order to factor can be found by listing out pairs of factors for the product of the last term and the coefficient of the first term, and using the two factors whose sum is the middle term.
For eg (because that was a bit text heavy):
The product of the last term and the first coefficient (1 * (-24)) is -24
the factors of -24 include (and their sum)
-1, 24 (23)
1, -24 (-23)
-2, 12 (10)
2, -12 (-10)
-3, 8 (5)
3, -8 (-5)
-4, 6 (2)
4, -6 (-2)
The middle coefficient is 5 and the sum of the factors -3 and 8 are 5, so split 5x into -3x + 8x to be able to factor how I showed before.
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.
