Problem |
Solve the equation: |
|
2 |
Step |
By using the factorisation method |
\$ x^2 - 6x + 4x -24 = 0 \$ |
3 |
Step |
After simplication we get |
\$ x(x-6) + 4(x-6) = 0 \$ |
4 |
Step |
Taking (x-6) has common |
\$ (x - 6)(x + 4) = 0 \$ |
5 |
Step |
We know that if ab = 0 then a=0,b=0 |
x - 6 = 0, x + 4 = 0 |
6 |
Step |
Moving constant terms to the left side |
x = 6 , x = -4 |
