-- Factor the left side of the equation.
-- Set one factor equal to zero, and solve it for 'x'. That gives you
one solution to the equation.
-- Set the other factor to zero, and solve it for 'x'. That gives you
the other solution to the equation.
-- If you don't get x=2 and x=-8/3 then repeat the previous steps,
because you made a mistake the first time.
Without knowing what "x" is, we cannot say what the answer will be. And without knowing the answer, we cannot solve for "x". Set x at zero, for example. Zero squared is zero, plus 6 time zero which is zero, minus 55. Your answer is then -55. Set x at one, for example. One squared is one, plus 6 times 1 which is six, minus 55. Your answer is then -48. Etc.
It can be solved by using the quadratic equation formula.
It can't be solved because the discriminant of this quadratic equation is less than zero
Factor it. (x - 8)(x - 2) x = 2, 8
That factors to (x + 1)(x - 3) x = -1, 3
It Equals 2
No. Zero is neither plus nor minus.
It can't be factored because its discriminant is less than zero.
x = 5 / 6squared + 7
x2-2x+1 = 0 (x-1)(x-1) = 0 x = 1 and also x = 1
