To solve for x in the equation x2 - 2x - 2 = 0, use the quadratic equation, that is:
For 0 = ax2 + bx + c, the roots (values of x) are defined as:
x = [-b +/- sqrt(b2 - 4ac) ] / 2a
(If that's hard to understand, Google "quadratic formula").
It works out to x = 2.73, -0.73.

What does x equal in 3x 4-11?
what does the equation equal? if it equals zero: 0= 3x(4-11) 0=3x(-7) 0=3x 0=x if the equation doesn't equal anything, it means it's just an expression meaning you can't solve for x, you can only reduce (and this equation is already reduced). if the equation equals y, you need another equation and use either substitution or elimination to solve for x.
Solve this equation y9 plus 5 equals 0?
correct anser is C ; y=-45

(4 ± i2) where i2 = -1
19 Solve this equation y 9 plus 5 0?
The answer to the equation 9 plus 5 times 0 equals 45. This was taught in 5 grade math.
What plus 5 equals 0?
The equation you are looking for is x + 5 = 0. To solve for x, you would subtract 5 from both sides of the equation. This would give you x = -5. Therefore, -5 plus 5 equals 0.
Solve this quadratic equation x2 plus 2x - 22 equals 0?
