The answer is going to be B hopefully this helps

This is the solution of the equation, where a=1, b=-5, c=7
So the discriminant is :
b^2-4ac=25-4*7= -3
The square root of -3 is non-real, this both solutions are non-real.
I think the answer is maybe A
First do with factor.
Factor 64x^2-9
Answer is = <span>(<span><span>8x</span>+3</span>)</span><span>(<span><span>8x</span>−3</span><span>)
It will help you.</span></span>
