First you should combine equal terms. For example, 2x2 and -4x2 can be combined as -2x2. Then you can use the quadratic formula.

Additonal Answer:-

2x2+5x+3-4x2+22 = 0

Collect like terms: -2x2+5x+25 = 0

Divide al terms by -1: 2x2-5x-25 = 0

Factorise: (2x+5)(x-5) = 0

Solutions are: x = -5/2 or x = 5
