Question

27x2-10+1=0

Open in App
Solution

Given: 27x2 - 10x + 1 = 0
Comparing the given equation with the general form of the quadratic equation ax2 + bx + c = 0, we get a = 27, b =-10 and c = 1.

Substituting these values in α = -b + b2 - 4ac2a and β = -b - b2 - 4ac2a, we get:

α= 10 + 100 - 4×27×12×27 and β = 10 - 100 - 4×27×12×27

α = 10 + 100 - 10854 and β = 10 - 100 - 10854

α = 10 + -854 and β = 10 - -854

α = 10 + 8i254 and β = 10 - 8i254

α = 10 + i2254 and β= 10 - i2254

α = 2(5 + i2) 54 and β = 2(5 - i2)54

α = 527 + 227i and β= 527 - 227i


Hence, the roots of the equation are 527 ± 227i.
