which of the following is a factor of x2 - 5x - 6
7(x - 2)(x + 2)
Two to the fourth power times 5 to the fourth power equals 10,000
This is like a² - b², with a = 9x² and b = 9y². This can be factored as (a - b)(a + b), then substitute for a & b: (9x² - 9y²)(9x² + 9y²), then (9x² - 9y²) can factor to (3x - 3y)(3x + 3y) so we have: (3x - 3y)(3x + 3y)(9x² + 9y²)
0.6 to the fourth power equals 0.1296
It is: (x-y)4
(x2 + 1)(x2 - 2)
2x to the fourth power minus 162 equals -146
x^2(x - 4)(x + 4)
No.
x cubed minus 216
(3x^2 - 4y^2)(3x^2 + 4y^2)
4(10x4 + 3)(10x4 - 3)
There is a formula for the "difference of squares." In this case, the answer is (x2 - 5)(x2 + 5)
(x4 - 16) = (x2 + 4) (x2 - 4) = (x2 + 4) (x + 2) (x - 2)
Factor x4 - 81. Step 1: both numbers have square roots and have a minus sign between them so the first factor result is (x2+9)(x2-9). Step 2: (x2+9) does not factor, but (x2-9) factors to (x+3)(x-3). Step 3: Solution is (x2+9)(x+3)(x-3).
