2X - 6X + 5 = 0
subtract 5 from each side
2X - 6X = - 5
do what it says on the left
- 4X = - 5
X = 5/4
check in original equation
2(5/4) - 6(5/4) + 5 = 0
10/4 - 30/4 + 5 = 0
- 20/4 + 5 = 0
- 5 + 5 = 0
0 = 0
checks
0. Any equation that has times 0 equals 0.
a = 0
5
The equation you are looking for is x + 5 = 0. To solve for x, you would subtract 5 from both sides of the equation. This would give you x = -5. Therefore, -5 plus 5 equals 0.
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
-5
x=0

(1, 0)
No.
x3 + 2x2 - 8x + 5 = 0 x(2x - 8) + 5 = 0
the answer is 0
