[tex] \large{f(x) = g(x)} \\ \large{ {x}^{2} + 3x = x + 3}[/tex]

Since we are solving the quadratic equation because the highest degree in the equation is second. We arrange in the form of ax²+bx+c = 0.

[tex] \large{ {x}^{2} + 3x - x - 3 = 0}[/tex]

Combine like terms.

[tex] \large{ {x}^{2} + 2x - 3 = 0}[/tex]

Solve the equation by factoring.

[tex] \large{(x + 3)(x - 1) = 0} \\ \large{x = - 3,1}[/tex]

Hence the values of x that make f(x) = g(x) are -3 and 1.

Answer

  • x = -3,1
