X2+0X - 2.25=0
1.= Both sides by 2.25
X2+0X=2.25
2. Subtract both sides by 0X
X2=2.25
3. Square root both sides
X=1.5

x2 = 8xx2- 8x = 0x(x - 8) = 0x = 0 ;x - 8 = 0x = 8

y = 2x - x2y = 0Since both quantities on the right side are equal to 'y', they're equal to each other.2x - x2 = 0x (2 - x) = 0x = 0and2 - x = 0x = 2The two points of intersection are (0, 0) and (2, 0) .
x2 - 5x + 6 = 0(x - 2) (x - 3) = 0x - 2 = 0 5 × 69 or x - 3 = 0x = 2 or x = 3
