Write the quadratic equation in standard form and then choose the value of "b." (2x - 1)(x + 5) = 0

Solution:

The general form of a quadratic equation is given by ax² + bx + c = 0.

We have been given equation in the form of (2x - 1)(x + 5) = 0

On solving this we get, 2x² + 9x - 5 = 0

If we compare 2x² + 9x - 5 = 0 with the general form of quadratic equation that is ax² + bx + c = 0

We can say that 2x² + 9x - 5 = 0 is in its general form with a = 2, b = 9, c = -5

Thus, the value of b is 9.

Write the quadratic equation in standard form and then choose the value of "b." (2x - 1)(x + 5) = 0

Summary:

2x² + 9x - 5 = 0 is in its general form with a = 2, b = 9, c = -5. Thus, the value of b is 9.
