( | 3 2 | + | 2 | x | ) | ( | 1 | + | 2 | x | ) | = | 3 |
Left side of the equation = | 3 2 | ( | 1 | + | 2 | x | ) | + | 2 | x | ( | 1 | + | 2 | x | ) |
= | 3 2 | × | 1 | + | 3 2 | × | 2 | x | + | 2 | x | ( | 1 | + | 2 | x | ) |
= | 3 2 | + | 3 | x | + | 2 | x | ( | 1 | + | 2 | x | ) |
= | 3 2 | + | 3 | x | + | 2 | x | × | 1 | + | 2 | x | × | 2 | x |
= | 3 2 | + | 3 | x | + | 2 | x | + | 4 | x | x |
= | 3 2 | + | 5 | x | + | 4 | x | x |
3 2 | + | 5 | x | + | 4 | x | x | = | 3 |
x1= | - | 3 2 |
x2= | 1 4 |
