It is 2n^3 + 7n^2 - 13n + 3
By factoring I get x-3 divided by x+3
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
(a - 2)(a^2 + 6)
X= plus or minus 1
Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.
(x-1)(x+2)
That can be factored to (x - 2)(x - 1)
Factor out -2: -2(x squared +11x-20). This is fully factored.
It is a quadratic equation in X, with two real roots.
Five squared is 25, and two squared is 4. When you add these together, 25 plus 4 equals 29. Therefore, five squared plus two squared is 29.
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: 1 plus or minus i where i is the square root of negative one.
x2-9x+8=0 has two solutions:x = 8x = 1
