Astudent is deriving the quadratic formula. her first two steps are shown.

step 1: –c = ax2 + bx

step 2: -c = a[x^2+b/ax]

which best explains or justifies step 2?

division property of equality

factoring the binomial

completing the square

subtraction property of equality

The polynomial in its standard form is:

The student's first step is:

The student's second step is:

The student's second step is to factor the remaining binomial on the right side of the equation.

In this case, the student made a common factor of the letter a.

The sentence that best explains or justifies Step 2 is:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
