2x^2 + 10 = 9x
subtract 9x from both sides, so you have:
2x^2 - 9x + 10 = 0
Factor this to
(2x-5)(x-2) = 0
Two solutions
x = 2
and
2x = 5
x = 2.5
subtract 9x from both sides, so you have:
2x^2 - 9x + 10 = 0
Factor this to
(2x-5)(x-2) = 0
Two solutions
x = 2
and
2x = 5
x = 2.5

2x^2+9x+10
2x^2+4x+5x+10
2x(x+2)+5(x+2)
(x+2)(2x+5)=0
(x+2)=0 or(2x+5)=0
x=-2 or x=-5/2
