(4a+b).(2ab) = 0 8a²b+2ab²=0
8a²b+2ab²=0 8(10 / b+ab²) + 2ab² = 0
a²b+ab² = 0/-8-2 (8b + 8ab² + 10 / b + ab²) + 2ab² = 0
a²b+ab²= 0 / -10 8+8+10 +2ab²=0
a²b+ab² = 10 26 + 2ab² = 0
a²= 10 / b+ ab² 2ab² = - 26
ab²= - 26² = - 13
8a²b+2ab²=0
8*(10/ b + ab²) + 13
(8b+8ab²+10 / b+ ab²) + 13 = 0
(8b+(-13) + 10 / b + (-13) ) +13 = 0
8+10+13 = x
x= 31
8a²b+2ab²=0 8(10 / b+ab²) + 2ab² = 0
a²b+ab² = 0/-8-2 (8b + 8ab² + 10 / b + ab²) + 2ab² = 0
a²b+ab²= 0 / -10 8+8+10 +2ab²=0
a²b+ab² = 10 26 + 2ab² = 0
a²= 10 / b+ ab² 2ab² = - 26
ab²= - 26² = - 13
8a²b+2ab²=0
8*(10/ b + ab²) + 13
(8b+8ab²+10 / b+ ab²) + 13 = 0
(8b+(-13) + 10 / b + (-13) ) +13 = 0
8+10+13 = x
x= 31
