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
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

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.
x can be anything, if you don't have it in an equation form, can an be an infinite amount of 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
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
