Subtract x from both sides:

2x%5E2-11x%2B20=0

Maybe factorable, but without looking to see,
x=%2811%2B-+sqrt%28121-4%2A2%2A20%29%29%2F%282%2A2%29
x=%2811%2B-+sqrt%28121-160%29%29%2F4
x=%2811%2B-+sqrt%28-39%29%29%2F4
highlight%28x=%2811%2B-+i%2Asqrt%2839%29%29%2F4%29



In fact it was not factorable. Also, the solutions are Complex with imaginary parts.
