Question 4 • FL-1200330-Algebra 2 CR

Which system of equations can you use to find the roots of the equation?x3 – 10x = x2 – 6

Answer
A
y = x3 – x2 + 10x + 6y = 0
B
y = x3 – x2 + 10xy = 6
C
y = x3 – 10xy = x2 – 6

Explanation

The original equation already sets two expressions equal: x³ − 10x and x² − 6. Graph each expression as a separate equation, so the system is y = x³ − 10x and y = x² − 6. Their intersection points have x-coordinates that are the roots, so the correct choice is C.
