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
That equation has no solutions.There's no number that can go in place of 'x' that canmake the equation a true statement.
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.
its a math equation
36.74 + 39.31 + 35.08 = 111.13
4
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.
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.
