What is the real solution for the equation x2-8x-4 equals 0?
I'll show work. X2-8x-4=0. X2-8x=4. X-8x=2. -7x=2. X=-(2/7).
Explain how to solve x2 plus 8x -2 equals 0 by completing a square?
x2 + 8x - 2 = 0 => x2 + 8x = 2 => x2 + 8x + 16 = 2 + 16 = 18 => (x + 4)2 = 18 => x + 4 = +or- sqrt(18) = +or- 3*sqrt(2) so x = -4 +or- 3*sqrt(2)
Factor the trinomial x2 plus 8x plus 12?
x2 + 8x + 12 = (x + 6) (x + 2)
What is the Factored form of x squared -8x plus 15?
X2 - 8X + 15 = (X - 3)(X - 5)
X2 plus 8x 12 equals 0 in quadratic formula?
x2+8x+12 = 0 When factorized: (x+6)(x+2) = 0 Therefore: x = -6 or x = -2
Can you factor x2 plus 8x plus 64?
No because the discriminant is less than zero.
What is the quadratic function for the zeros -4 and -4?
0
Is fx -x2 a function?
f(x) = -x2 is a function. The equation is solved with just f(x) on one side, and if you were to graph it, it would pass the vertical line test.
Which statement best describes the function below fx equals x3-x2-9x 9?
A cubic.
What is X2 plus 8X plus 16?
X2 + 8x + 16 = 10x +16x2 + 8x + 16=2x + 8x + 16=10x + 16
What does x equal in x2-8x equals 0?
x2-8x=0 ( add 8x to both sides) x2 =8x (divide by x) x=8 ( x2divided by x equals x)
What is 4xsquared 8x - 24 factored?
If that's + 8x, the answer is 4(x2 + 2x - 6) If that's - 8x, the answer is 4(x2 - 2x - 6)
X2 -8x equals 1?
x2 - 8x = 1 ∴ x2 - 8x + 16 = 17 ∴ (x - 4)2 = 17 ∴ x - 4 = ±√17 ∴ x = 4 ± √17
What are the factors of x2 plus 8x - 20?
x2 + 8x - 20 = (x - 2)(x + 10).
Factor x2 plus 8x?
x2 + 8x = x(x+8)
What is the real solution for the equation x2-8x-4 equals 0?
I'll show work. X2-8x-4=0. X2-8x=4. X-8x=2. -7x=2. X=-(2/7).
Y equals x2 plus 8x plus 15?
y = x2 + 8x + 15 = (x + 3)(x + 5). When y = 0, one or other of the two factors must equal zero; that is, x = -3 or -5, when y = 0.
