Question

Write the equation 0.3x2 + 5x - 7 =0 in general form and then choose the value of "b."

Answer 1

For this case we have that by definition, an equation of the second degree is given by:

`ax ^ 2 + bx + c = 0`

We have the following equation:

`0.3x ^ 2 + 5x-7 = 0`

Then, according to the definition above, we have to:

`a = 0.3\\b = 5\\c = -7`

Thus, b equals 5.

Answer:

`b = 5`
