4 is a factor of each of your terms, so take out a 4 first. Then recognize that -3 + -4 = -7 and (-3)(-4) = 12….SOLUTION: Factor 4x^2-28x+48 pleaseeeeee.
| First Number | Second Number | Sum |
|---|---|---|
| 3 | 4 | 3+4=7 |
| -1 | -12 | -1+(-12)=-13 |
| -2 | -6 | -2+(-6)=-8 |
| -3 | -4 | -3+(-4)=-7 |
What is the factor of 4×2 81?
Rewrite 4×2 4 x 2 as (2x)2 ( 2 x ) 2 . Rewrite 81 as 92 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 – b 2 = ( a + b ) ( a – b ) where a=2x a = 2 x and b=9 .
How do you factor 4x 12?
What is the common factor in 4x + 12 ?
- 1 Answers. #1. +4. In 4x + 12, both 4x and 12 are divisible by 4, so 4 is the common factor. One can factor 4x + 12 as 4*(x + 3). I have no idea what you are on about in the rest of your question! Alan Feb 27, 2020. edited by Alan Feb 27, 2020.

What are the factors of 4x² 49?
Rewrite 4×2 4 x 2 as (2x)2 ( 2 x ) 2 . Rewrite 49 as 72 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 – b 2 = ( a + b ) ( a – b ) where a=2x a = 2 x and b=7 .
Is 4x 2 perfect square?
The first term, 4×2, is the square of 2x, and the last term, 36, is the square of 6 (or, in this case, –6, if this is a perfect square). this is not a perfect square trinomial.
How to calculate factor 4x ^ 2-28x + 49?
Check that the middle term is two times the product of the numbers being squared in the first term and third term. Rewrite the polynomial. Factor using the perfect square trinomial rule a2 − 2ab+b2 = (a−b)2 a 2 – 2 a b + b 2 = ( a – b) 2, where a = 2x a = 2 x and b = 7 b = 7.
