Question

listen
what is the resulting quadratic equation when you substitute $y$ with $4x - 2$ in the equation $y = x^2 - 4x + 5$?
use the standard form of a quadratic equation.
use the keypad to enter your answer in the box. more symbols can be found using the drop-down arrows at the top of the keypad.
the reduced quadratic equation is $square$.

Explanation:

Step1: Substitute $y=4x-2$

$4x - 2 = x^2 - 4x + 5$

Step2: Rearrange to standard form

$x^2 - 4x + 5 - 4x + 2 = 0$

Step3: Combine like terms

$x^2 - 8x + 7 = 0$

Answer:

$x^2 - 8x + 7 = 0$
