Question

what is the first step in solving a quadratic equation of the form given below.
(ax+b)^2=c
A.) Take the square root of both sides.
B.) Use the zero product rule.
C.) Divide both sides by c.
D.) Factor out the common factor.

Answer 1

Answer:

Given the quadratic equation

(ax+b)^2=c(ax+b)

2

=c

we have to define the first step in solving a quadratic equation.

To find the value of x we have make the equation linear i.e taking the square root on both sides as c is any constant.

If c is 0 the we use the zero product rule.

Hence, our first step in solving a quadratic equation of the form

(ax+b)^2=c(ax+b)

2

=c

is to take the square root of both sides.

Correct option is D.
