x2-64 = (x-8)(x+8)
No. Trial and error is the most inefficient way for factoring.
Multiplying.
It means you are required to "solve" a quadratic equation by factorising the quadratic equation into two binomial expressions. Solving means to find the value(s) of the variable for which the expression equals zero.
Infinity
Yes
x264 is an encoder only, so you don't need it to watch videos. If you're talking about encoding video, then you can use programs like HandBrake or MeGUI to encode your videos using x264.
Software library x264 is used for decoding video streams. The x264 software was developed in 2004 by Laurent Aimar. The software library x246 can be downloaded for free.
When the co-efficient of x2 is 1
Solve by factoring. Solve by taking the square root of both sides.
Solve by factoring.2x2 - 3x + 1 = 0
-(x - 1)(x2 + x + 1)
X2 - Y2 = (X + Y)(X - Y)
The discriminant for the quadratic is b2-4ac = 302 - 4*4*45 = 900 - 720 = 180 Since 180 is not a perfect square, the roots of the equation are irrational and it is far from straightforward to solve such an equation by factoring.

To solve a quadratic equation by factoring, first express the equation in the standard form ( ax^2 + bx + c = 0 ). Next, look for two numbers that multiply to ( ac ) (the product of ( a ) and ( c )) and add up to ( b ). Rewrite the middle term using these two numbers, then factor the quadratic expression into two binomials. Finally, set each binomial equal to zero and solve for ( x ).
x264: Without knowing the value of x you cannot evaluate this expression.
