Begin by noticing that your factor pairs will have the form ( __x + __)(__x - __). Remember that the two ends are products, and the middle number is a sum. Find the factor pairs for each end number. 4 3 1 and 4 1 and 3 2 and 2 Since 3 only has one option, you know either: ( __x + 1)(__x - 3) or (__x - 1)(__x + 3) then start testing the factor pairs of 4. I like to start with the closest together pair - 2 and 2 here. Do 2 x 1 and 2 x 3 subtract to give you 4? Yes! 6 - 2 = 4! So I want the 6 positive and the 2 negative. This gives me (2x + 3)(2x - 1).

What is the correct factorization of the expression 12x2 - 4x3?
Take out the common factor, which in this case is 4x2. Divide each of the terms by this common factor. 12x2 - 4x3 = 4x2(3+x)
What are the factors of 4x3 plus 10x2 plus 2x plus 5?
4x3+10x2+2x+5= (2x+5)(2x2+1)
How do you find multiples of 4?
Start with 4 and keep multiplying it. Maybe start with 4x1 then 4x2 then 4x3 etc. You have 4,8,12, etc.
What answer is equal to the sum in the expression below (3x3 plus 4x2 - 2x plus 1) plus (x4 - x3 plus 5x2 plus 2x plus 3)?
Answer this question…A. x4 + 2x3 + 9x2 + 4 B. x4 + 4x3 + 9x2 + 4 C. x4 + 2x3 + 9x2 + 4x + 4 D. x4 + 2x3 + 9x2 - 4x + 4
What is x if 4x3 plus 50x equals 250?
4x3=12 250-12=238 238/50=4.76
