Question

find the value of discriminant
1). x² + 7 x - 1 = 0

Answer 1

your answer is given above

Answer 2

Here is the answer

Given Equation =>
$\bf{{x}^{2} + 7x - 1 = 0}$
Comparing the given Equation with ax^2 + bx + c = 0.

We get,
a = 1
b = 7
c = -1

$\bf {\triangle = {b}^{2} - 4ac}$
$\bf{ = ( {7)}^{2} - 4(1) \times ( -1 )}$
$\bf {= 49 + 4}$
$\bf {= 53}$

This
Value of the discriminant is 53.

Thanks!!
