None of the items on the list that accompanies the question
satisfies that description.
2x2 + 2x - 60
= 2(x2 + x - 30), b = 1 and c = -30
= 2(x + 6)(x - 5) since 6*-5 = -30 and 6 + -5 = 1
X= plus or minus 1
(x - 16)(x + 2) x = 16 or -2
It's about 34 and a third
The answer is 4 squared minus 2 squared as 4 squared is 16 minus 2 squared, which is 4, gives you 12 as an answer.
One plus cosecant squared x is equal to cotangent squared x.
-22 - -22
Remember to factor out the GCF of the coefficients if there is one. A perfect square binomial will always follow the pattern a squared plus or minus 2ab plus b squared. If it's plus 2ab, that factors to (a + b)(a + b) If it's minus 2ab, that factors to (a - b)(a - b)
By factoring I get x-3 divided by x+3
X= plus or minus 1
Without knowing what "x" is, we cannot say what the answer will be. And without knowing the answer, we cannot solve for "x". Set x at zero, for example. Zero squared is zero, plus 6 time zero which is zero, minus 55. Your answer is then -55. Set x at one, for example. One squared is one, plus 6 times 1 which is six, minus 55. Your answer is then -48. Etc.
(x - 16)(x + 2) x = 16 or -2
Why don't you figure it out yourself
x2-81=(x-9)(x+9) Factors: x-9, x+9
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.
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: -2 plus or minus i times the square root of 17.x = -2 + 4.123105625617661ix = -2 - 4.123105625617661iwhere i is the square root of negative one.
