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.
A polynomial.
(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.
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.
2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----
