Question

please answer? options for the second box: (there is no solution) (there is one solution) (there is two solution)

Answer 1

Solution

We are given

$y=4x^2+15x-4$

Here

$\begin{gathered} a=4 \\ b=15 \\ c=-4 \end{gathered}$

The discriminant D is

$\begin{gathered} D=b^2-4ac \\ D=15^2-4(4)(-4) \\ D=225+64 \\ D=289 \end{gathered}$

Since, the discriminant is positive, we have two x- intercept
