Looking at the function:
x2 + 12x + 28
We know that in order to factor it, we would need two numbers whose product is equal to 28 and whose sum is equal to twelve. We know they must both be positive, as both their sum and their product are positive. That means our possible numbers to combine are all the positive factors of 28:
1, 2, 4, 7, 14, 28
As it happens, no two of these will add up to 12, which tells us that yes, the original polynomial is prime.

-2x+12x+28=10x+28 ;Combining like factors2(5x+14) ; Factor out a two from both of them
What is the factor of the trinomial below negative x2 plus 12x plus 28?
I would do this. Multiply through by -1 -1 ( -X^2 +12X +28 ) = X^2 -12X -28 (X+2)(X-14)
12x-28 equals -63 plus 7x?
12x - 28 = 7x - 63Subtract 7x from each side:5x - 28 = -63Add 28 to each side:5x = -35Divide each side by 5:x = -7

12x-28 equals 18x-88 what is x?
12x - 28 = 18x - 88Put the variables on one side and the constants on the other by subtracting 12x from both sides and adding 88 to both sides. 12x - 12x - 28 + 88 = 18x - 12x - 88 + 88 Simplify 60 = 6x Divide both sides by 6 x = 10 If you want to check your answer, which is always a good idea, plug in 10 for x in the original expression and see if you get a true statement: 12(10) - 28 = 18(10) - 88 120 - 28 = 180 - 88 92 = 92
How do you solve the equation 8x 12x 28?
