# How do you factor 2x2 plus 10x plus 11 equals 0?

a = 2, b = 6, c = 5

x = (-b plusminus sqrt(b2 - 4ac))/2a

x = (-6 plusminus sqrt(36 - 40))/4

x = (-6 plusminus sqrt(-4))/4

As you can see, this has resulted in the square root of a negative number, which is not usually possible. You may not need to know about imaginary numbers yet, but the solution to this can actually be given using the imaginary constant, i, with the answer being a complex number (a real number combined with an imaginary number).

x = (-6 plusminus 2i)/4

x = -3/2 + i/2 and -3/2 - i/2

That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (-5 plus or minus the square root of 3) divided by 2

x = -1.6339745962155614

x = -3.3660254037844384

2x2 - 5x - 3 = 0

This equation can be factored :

(2x + 1)(x - 3) = 0

It can't be factored because its discriminant is less than zero
