Q. 15

Solve the following quadratics17x2 + 28x + 12 = 0

Answer :

Given 17x2 + 28x + 12 = 0

Recall that the roots of quadratic equation ax2 + bx + c = 0, where a ≠ 0, are given by

Here, a = 17, b = 28 and c = 12

We have i2 = –1

By substituting –1 = i2 in the above equation, we get

Thus, the roots of the given equation are.
