please me solve this equation: -22x^2+55x-14

that is not an equation
that is a trinomial (a polynomial with 3 terms)
if it were an equation it would be:
-22x^2 + 55x - 14 = 0
this can be solved using the quadratic formula
for ax^2 + bx + c = 0, a = -22, b = 55, c = -14 in this case
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

Quadratic equation ax%5E2%2Bbx%2Bc=0 (in our case -22x%5E2%2B55x%2B-14+=+0) has the following solutons:

x%5B12%5D+=+%28b%2B-sqrt%28+b%5E2-4ac+%29%29%2F2%5Ca

For these solutions to exist, the discriminant b%5E2-4ac should not be a negative number.

First, we need to compute the discriminant b%5E2-4ac: b%5E2-4ac=%2855%29%5E2-4%2A-22%2A-14=1793.

Discriminant d=1793 is greater than zero. That means that there are two solutions: +x%5B12%5D+=+%28-55%2B-sqrt%28+1793+%29%29%2F2%5Ca.

x%5B1%5D+=+%28-%2855%29%2Bsqrt%28+1793+%29%29%2F2%5C-22+=+0.287640210920903
x%5B2%5D+=+%28-%2855%29-sqrt%28+1793+%29%29%2F2%5C-22+=+2.2123597890791

Quadratic expression -22x%5E2%2B55x%2B-14 can be factored:
-22x%5E2%2B55x%2B-14+=+-22%28x-0.287640210920903%29%2A%28x-2.2123597890791%29
Again, the answer is: 0.287640210920903, 2.2123597890791. Here's your graph:

this is a statement not an equation. It has no equal sign.
