9x2+x+64 9*64=576
To skip all this confusion, I graphed it and it does not have a solution.
When you graph it, it should cross the x-axis. When it does, the two places that it does is the solution.

X2 plus 12x-64 equals 0?
x2 + 12x - 64 = 0 ∴ (x + 16)(x - 4) = 0 ∴ x ∈ {4, -16}
If 64 plus x squared equals 196 what is x?
64 + x2 = 196 Therefore, 196 - x2 = 64 x2 = 132 Therefore, x = sqrt(132). Rounded to three decimal places, this is equal to 11.489.
X2 plus 5x plus 3 equals 9?
x2 + 5x + 3 = 9 x2 + 5x - 6 = 0 (x + 6)(x - 1) = 0 x = -6 or x = 1
Is x2-6x plus 9 can factor?
x2-6x+9 = (x-3)(x-3) when factorised.
What is -x2 plus 7x plus 18?
-(x - 9)(x + 2)
X2 plus 12x-64 equals 0?
x2 + 12x - 64 = 0 ∴ (x + 16)(x - 4) = 0 ∴ x ∈ {4, -16}
What is the solution of x2 plus 24x plus 144 equals 9?
x2+24x+144 = 9 x2+24x+144-9 = 0 x2+24x+135 = 0 (x+9)(x+15) = 0 x = -9 or x = -15
If 64 plus x squared equals 196 what is x?
64 + x2 = 196 Therefore, 196 - x2 = 64 x2 = 132 Therefore, x = sqrt(132). Rounded to three decimal places, this is equal to 11.489.
What is X2-4x plus 9 when x equals -8?
If [ x = -8 ], thenx2 - 4x + 9= (-8)2 - 4(-8) + 9= 64 + 32 + 9= 105
What is the answer to x2 plus 9 equals 10x?
x2 + 9 = 10x x2 - 10x + 9 = 0. (x - 9)(x - 1) = 0. Therefore, x = 1 or 9.
How do you factor x cubed plus 4x squared plus 16x plus 64?
x3 + 4x2 + 16x + 64 =x2*(x + 4) + 16(x + 4) = (x + 4)*(x2 + 16) which has no further real factors.
Factorization of x2 plus 12x plus 27?
x2 + 12x + 27 = (x + 9)(x + 3)
What does x squared plus 14 plus 48 divided by x plus 8?
(x2 + 14 + 48 / (x + 8) = (x2 + 62) / (x + 8) =(x2 + 8x - 8x - 64 + 126) / (x + 8) = x - 1 + 126/(x+8)
X2 plus 5x plus 3 equals 9?
x2 + 5x + 3 = 9 x2 + 5x - 6 = 0 (x + 6)(x - 1) = 0 x = -6 or x = 1
Factor the polynomial x2 plus 10x plus 9?
(x+1)(x+9)
Is x2-6x plus 9 can factor?
x2-6x+9 = (x-3)(x-3) when factorised.
X2 plus 7x plus 9 equals 3?
x2 + 7x + 9 = 3 ∴ x2 + 7x + 6 = 0 ∴ (x + 6)(x + 1) = 0 ∴ x ∈ {-6, -1}
