x2+12x+11=0 (x+11)(x+1)=0 x=-11 or x=-1
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
How do you factor 2x2 - 13x - 7?
2x2 - 13x - 7 = (2x + 1)(x - 7)
What is 13(x-1) 6?
If you mean: 13*(x -1) +6 then it is 13x -13 +6 = 13x -7 as an expression
Solve for x. 9 equals 12 - 3x?
x . 9 =12-3x9x =12-3x9x+3x=1212x =12x =1
Need help to solve this equation 3-x equals 12x-1?
3 -x = 12x -1 add x to both sides 3 = 13x -1 add 1 to both sides 4 = 13X divide both sides by 13 4/13 = x
Can you help solve 3-x equals 12x-1?
3 - x = 12x - 1 Add x to both sides of the equation: 3 = 13x - 1 Add 1 to both sides of the equation: 4 = 13x Divide both sides of the equation by 13: 4/13 = X
