Use the quadratic formula: (-b +/- sqrt(b2 - 4ac))/2a
in your example a = 9, b = 4 and c = 5 giving:
(-4 +/- (sqrt (16 - 180))/18
This has no real solution as it involves the square root of a negative number.
If you've got your signs wrong possible solutions are:
(9x + 5)(x - 1) = 9x2 - 4x - 5
or ((9x - 5)(x + 1) = 9x2 + 4x - 5

How do you Solve -4x plus 5 plus 9x - 2?
There is no equation, only an expression. An expression can be simplified but cannot be solved.
How do you solve 2y equals 4x plus 4?
2y = 4x + 4y = 2x + 2
Solve for x when 4x plus 2 2x - 10?
4x+2=2x-102x=-12 x=-6
What is the answer to 5x - 2 4x plus 4?
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
9x-3x minus 12 plus 10 equals 2x plus 18 plus 4x-20?
this is the same as 6x - 2 = 6x - 2! There are an infinite number of possibilities for "x".
How do you Solve -4x plus 5 plus 9x - 2?
There is no equation, only an expression. An expression can be simplified but cannot be solved.
Solve 4x plus 5x equals 60?
9x = 60x = 60/9 = 6 2/3 (or 6.67)
What is the answer to 9x plus 3-25 equals 4x-2?
9x+3-25 = 4x-2 5x = 20 x = 4
What is 9x squared plus 4x - 2?
It is a quadratic equation in x.
What does x equal if 4x-13x 2?
If you mean 4x-13x = 2, then-9x = 2-9x/-9 = 2/-9x = -2/9
9x plus 5 equals 4x plus 3?
9x + 5 = 4x + 3 Subtract 4x from both sides: 5x + 5 = 3 Subtract 5 from both sides: 5x = - 2 Divide both sides by 5: x = -2/5 or -0.4
How do you solve -9x-3 plus 4x equals -2x?
Equation: 9X-3+4X=-2X You are going to want to factor this equation into something that looks like X=35, 35 being a randomly selected number. Step 1) Add 3 to both sides 9X+4X=-2X+3 Step 2) Add 2X to both sides 9X+4X+2X=3 Step 3) Simplify 15X=3 Step4) Divide both sides by 15 X=3/15
How do you solve 2y equals 4x plus 4?
2y = 4x + 4y = 2x + 2
How do you factor 4Xsquared-24X plus 9X?
This may be copied wrong, but as written that equals 4x^2-15x which factors to x(4x - 15)
How do you solve 5 plus 4x - 7 equals 4x plus 3 - 1x?
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
How do you solve x plus 2 equals -4x plus 7?
Add 4x - 2 to each side: 5x = 5 x = 1
Which of the following is an x-intercept of y -36x2 - 55x 14?
y = -36x2 - 55x + 14; since -36(14) = 4(-9)(7)(2) = 8(-63) and 8 + (-63) = -55, then y = (-36x2 - 63x) + (8x + 14); factor out -9x and 2 y = -9x(4x + 7) + 2(4x + 7); factor out 4x + 7 y = (4x + 7)(-9x + 2); let y = 0 0 = (4x + 7)(-9x + 2); let each factor equal to zero and solve for x 4x + 7 = 0 or -9x + 2 = 0 x = -7/4 or x = 2/9 Thus, the parabola cuts the x-axis at -7/4 and 2/9.
