What is the discriminant of the quadratic equation 2x + 5x2 = 1?

The discriminant of the quadratic equation is 24 .

Step-by-step explanation:

Discriminant form of the quadratic equation .

D = b² - 4ac

As the quadratic equation in the form.

2x + 5x² = 1

Simplify the above term

5x² + 2x -  1 = 0

As the quadratic equation in the form

ax² + bx + c =0

Here a = 5 , b = 2 , c= -1

put in the formula

D = 2 × 2 - 4× 5 × -1

D = 4 +20

D = 24

Therefore the discriminant of the quadratic equation 5x² + 2x -  1 = 0 is 24 .

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
