Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.
What we can see is two expressions: not an equation (or inequality) which can be solved.
If you mean: x squared -14x +45 then when factored it is (x-9)(x-5)
(x-3)(x+2)the answer is x=3
(x-3)(x-2)
x2+x-15 = 0 Using the quadratic equation formula: x = 3.405124838 or x = -4.405124838
x=9 squared
To solve for x: 2x2 + 10 = 58 2x2 = 48 x2 = 24 x = √24 x = √4 × √6 x = 2√6
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
X squared = x+6 6+x=x squared X=6
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
Divide each side by -15 and x = - 6/15.

With great difficulty because in the absence of an equality sign it has no solutions but it is just some kind of algebraic expression.
