Question

Write the equation 0.3x^2+5x-7=0 in standard form and then choose the value of “b”

Answer 1

Answer:

b = 5

Step-by-step explanation:

The given equation is :

$0.3x^2+5x-7=0$ .......(1)

It is in the form of quadratic equation. The general form of a quadratic equation is as follows :

$ax^2+bx+c=0$ .....(2)

Comparing equations (1) and (2), we get :

a = 0.3, b = 5 and c = -7

Hence, the value of b is equal to 5.
