It often helps to take square roots on both sides of the equation. However, solutions to the original equation may be lost - it is often convenient to put a "plus or minus" sign so as not to lose solutions. Example: x2 = 25 Taking square roots: x = "plus or minus" 5
No. It's a quadratic equation, and it has two solutions.
None because without an equal it is not an equation. But if it was in the form of x2+7x+12 = 0 then it would have 2 solutions which are x = -3 and x = -4
None because without an equal sign it's not an equation
2 this Domo
The equation -7 plus 12 equals out to be five. This is a math problem.
There are 120 solutions.
There are no real solutions because the discriminant of the quadratic equation is less than zero.

It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
No. It's a quadratic equation, and it has two solutions.

None because without an equal sign it's not an equation
There are 0, or no solutions to these equations. If you rearrange each equation to look like an equation of a line, you will have the two lines:y = x -1 and y = x + 1, which are two parallel lines. They do not intersect at any point, so there is no solution.
