It is (2x-5)(x-4) when factored

x2+x-380 = (x+20)(x-19) when factored

x2 = x+20 x2-x-20 = 0 (x-5)(x+4) = 0 x = 5 or x = -4

320 tolerance +/- 20 ? Did I get it right?

It can not be factored because its discriminant is less than zero

4, -5

(x+4)(x-5) = 0

Factor out -2: -2(x squared +11x-20). This is fully factored.

x squared plus 9x plus 20.

20

(x + 5) (x - 4)

20 = 400

'20 squared' simply means 20 multiplied by itself (20 x 20). This equals 400.

It is (2x-5)(x-4) when factored

The solutions are: x = 4, y = 2 and x = -4, y = -2
