X2 - 12X = 8
X2 - 12X - 8 = 0
Looks like a job for the quadratic formula.
X = - b (+/-) sqrt(b2 - 4ac)/2a
a = 1
b = -12
c = - 8
X = - (- 12) (+/-) sqrt[(- 12)2 - 4(1)(- 8)]/2(1)
X = 12 (+/-) sqrt(144 + 32)/2
X = 12 (+/-) sqrt(176)/2
X = [12 (+/-) 4sqrt(11)]/2

What is the solution to this equation x plus 12 equals -5?
7
What is the fifth step in solving the equation by completing the square 5x2-12x plus 4 equals 0?
x = 2 or x = 2/5
What is the x value of 12x - 5y equals 30 y equals 2x - 6?
Substitute 2x - 6 for y in first equation: 12x - 5(2x - 6) = 30 ie 12x - 10x + 30 = 30 so 2x = 0 making x = 0 and y = -6
How do you solve 12x equals 11x - 5?
12x = 11x - 5, subtract both sides by 11x x = -5
How do you solve -12x equals 6y?
its just a line, there are many answers that would work -12x-6y=0 -12x=6y x=-y/2 y=-2x
What is an equation that has the same solution as 8 - 5x equals x -10?
12x = 36
What is the solution of the following linear system 12x plus 6y equals 9 4x plus 2y equals 0?
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
What is the solution to this equation x plus 12 equals -5?
7
What is -12x plus -4y equals 2?
It is an equation.
What is the discriminant of the equation -3x square - 12x plus 7 equals 8?
The equation is equivalent to: -3x2 - 12x - 1 = 0 [you could change signs to get 3x2 + 12x + 1 = 0 but that is not required] The discriminant is (-12)2 - 4*(-3)(-1) = 144 - 12 = 132
What is the slope of the line with the equation y equals 12x?
12
What is 12x-7 equals 29?
An equation where x = 3
What statement describes the equation y equals 12x?
A function.
What is the slope of a line with the equation y equals 12x?
12
What is a solution of y-12x - 3?
The given expression has no solution because without an equality sign it can't be considered to be an equation.
What is the solution set for the equation 4 bracket 3x-2 bracket 2 equals 36?
4{3x-2}2=36 12x-8=18 12x=26 x=2.16666... I hope I read that equation right. If not, just message me and I can fix it.
True or false the solution of the equation of x squared plus 4x equals 0 is identical to the solution of 3x squared plus 12x equals 0?
True because in both equations x = 0 or x = -4
