1 |
Problem |
Solve the equation: |
|
2 |
Step |
By using the factorisation method |
\$ 5v^2 - 6v - 5v + 6 = 0 \$ |
3 |
Step |
After simplication we get |
\$ v(5v-6) - 1(5v-6) = 0 \$ |
4 |
Step |
Taking (5v-6) has common |
\$ (5v - 6)(v - 1) = 0 \$ |
5 |
Step |
We know that if ab = 0 then a=0,b=0 |
5v - 6 = 0, v - 1 = 0 |
6 |
Step |
Moving constant terms to the left side |
5v = 6 , v = 1 |
7 |
Step |
After simplication we get |
\$ v = 6/5 , v = 1\$ |
