Step-by-step explanation:
Slope = term that multiply x
y intercept = the number without a variable
Answer:
x = 1 or -5/2
Step-by-step explanation:
-2x^2 - 3x + 5 = 0
multiply all through by -1
2x^2 + 3x - 5 = 0
....... 2x^2 × 5 = 10x^2 = +5x × -2x
(2x^2 + 5x)-(2x - 5) = 0
x(2x + 5) - 1(2x + 5) = 0
x - 1 = 0 or 2x + 5 = 0
x = 1 or 2x = - 5
x = 1 or -5/2
