option b

hope it helps you

Answer 2

Answer:

(2) $\frac{-7}{2}$

Step-by-step explanation:

$2x^2+5x-7=0$

By splitting the middle term,

$2x^2-2x+7x-7=0$

$2x(x-1)+7(x-1)=0$

$(2x+7)(x-1)=0$

$x-1=0$

$x=1$

$2x+7=0$

$2x=-7$

$x=\frac{-7}{2}$

$x=1, \frac{-7}{2}$

$1$ × $\frac{-7}{2}$

$=\frac{-7}{2}$

∴ The product of the roots of the quadratic equation $2x^2+5x-7=0$ is (2) $\frac{-7}{2}$
