Write the quadratic equation in general form. what is the value of b2 - 4ac? 1 = 2x2 + 7x

The general form of quadratic equation is 2x² + 7x - 1 = 0 and value of  b² - 4ac is 57 .

Step-by-step explanation:

The standard form of quadratic equation is  ax² + bx + c = 0

Where  a, b, and c being constants, or numerical coefficients  and x is an variable.

As given the expression

1 = 2x2 + 7x

Simplify the above

2x² + 7x - 1 = 0

This is general form of quadratic equation .

a = 2 , b = 7 , c = -1

Putting all these values in the formula

= b² - 4ac

= 7 × 7 - 4 × 2 × -1

= 49 + 8

= 57

Therefore the general form of quadratic equation is 2x² + 7x - 1 = 0 and value of  b² - 4ac is 57 .

the answers c

the answer is 99.
