In mathematics, a solution set is the set of values that satisfy a given set of equations or inequalities.

so the sets are (x, y) which means you can input the x values and see which ones work

alones · Answer

To me it looks like
2x^2−3x−5=5−5
2x^2−3x−5=0
Step 2: Factor left side of equation.
(2x−5)(x+1)=0
Step 3: Set factors equal to 0.
2x−5=0 or x+1=0
x=5/2 or x=−1

what answers do you know are wrong

dayakar · Answer

2x^2-3x-5=0

2x^2 +2x -5x -5 =0  [ split the middle term]

2x*x +2x*1 -5x -5*1=0

2x(x+1) -5(x+1) =0

(x+1) (2x_1) =0

solve it
