Answer:
x = 1 and x= 2
Explanation:
First of all, divide all by 5.
x² - 3x + 2 =0
Using factorisation method, we need two numbers that add up to -3, but the same two numbers multiply with one another to produce answer of 2.
Format is (x ) (x ) = 0
-1 and -2, when added, produce result of -3. (-1 + -2 = -1 -2 = -3)
When multiplied, they give result of +2 (-1 X -2 = +2)
(x – 1) (x – 2) = 0. We have x – 1 = 0, x = 1. We also have x – 2 = 0, x = 2.
These are the solutions of the equation.
