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:

$b = 5$
