The discriminant (D) of a quadratic polynomial of the form $ax^2+bx+c$ is calculated using the following formula, where $a$, $b$ and $c$ are the coefficients of the corresponding terms

**

**

From the equation, we see that $a=-1$, $b=7$ and $c=-10$. Replacing the values of $a$, $b$ and $c$ in the previous formula, we obtain

**

Multiply $-1$ times $4$

**

**

Multiply $-4$ times $-1$

**

**

Multiply $4$ times $1$

**

**

Multiply $4$ times $-10$

**

**

Calculate the power $7^2$

**

**

Subtract the values $49$ and $-40$

**

**

The discriminant of the polynomial results in
