One solution.
It doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: 7 plus or minus i times the square root of 47b = 7 + 6.855654600401044ib = 7 - 6.855654600401044iwhere i is the square root of -1
4x-9(x plus 1)7-5x?
It is a quadratic equation that has 2 solutions
x can be anything, if you don't have it in an equation form, can an be an infinite amount of solutions

4x-9(x plus 1)7-5x?
It doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: 7 plus or minus i times the square root of 47b = 7 + 6.855654600401044ib = 7 - 6.855654600401044iwhere i is the square root of -1
7*3= 21
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: 7 plus or minus the square root of 38 x = 13.164414002968975 x = 0.835585997031024
1 is the answer
It is a quadratic equation that has 2 solutions
52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (3 plus or minus the square root of 2) divided by 7. x = 0.6306019374818707 x = 0.2265409196609864
x can be anything, if you don't have it in an equation form, can an be an infinite amount of solutions
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
