-2x + 6 - 13x + 16
= -15x + 22
Factor out the common terms in the first two terms, then in the last two terms;
3x^2(b - 3x) - (b - 3x)
Factor out the common term b - 3x
<u>= (b - 3x)(3x^2 - 1)</u>
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4
Answer:
The answer is x = 8/5
Step-by-step explanation:
6 - 5x + 2 = 3x - 12 + 2x
4 - 5x = 5x - 12
4 = 10x - 12
16 = 10x
8/5 = x
