Question

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

Answer 1

In general form the coefficient must be on whole number.
Given 0.3x2 + 5x - 7 = 0
times 10 throughout the whole equation

3x^2 + 50x - 70 = 0

the b value here is 50.

Answer 2

general form is ax^2+bx+c=0, and multiplying the given equation by 10 ,we get 3x^2 + 50x - 70 = 0 and hence b=50
