1. The value of k for which equation 9x2 + 8xk+8 = 0 has equal roots is:
Nesterboy [21]

Answer:

Option C

+ or - 3

Step-by-step explanation:

A quadratic equation will have equal roots if its Discriminant is equal to zero.

the discriminant in this case is b^{2}- 4 ac

considering the equation,

9x^{2} + 8xk+8 = 0

a = 9, b= 8k, c=8

Replacing the variables in the original equation with their respective values, we will have:

8k^{2}- 4 \times 9 \times 8=0\\64k^{2}=288\\k=\sqrt{288/64} =\sqrt{9/2}

Note: The values of k are meant to be + or -2.12 as seen from the workings

However, these are not in the options given. the closest choice to it

is + or - 3
