Question

Solve for x enter the solution from least to greatest x2 - 11x + 18 =0

Answer 1

x = 2 , 9

Explanation:

`{x}^(2) - 11x + 18 = 0`

`= > {x}^(2) - 9x - 2x + 18 = 0`

`= > x(x - 9) - 2(x - 9) = 0`

`= > (x - 9)(x - 2) = 0`

Here x will have 2 solutions.

1)
`x - 9 = 0`

`= > x = 9`

2)
`x - 2 = 0`

`= > x = 2`

Hence the 2 solutions of x are +2 & +9
