Equation: y= x^2 - 8x + 12

Working out y intercept:

Complete the square

y= (x - 4)^2 - 4

(-4^2) - 4 = 12

y intercept is (0,12)

Working out x intercept:

Factorise

x^2 - 8x + 12

x^2 - 6x - 2x + 12

x (x - 6) -2 (x - 6)

(x - 6) (x - 2)

x = 6 and x = 2

x intercepts are (6,0) and (2,0)

Thank You!!

i already took the test and i think i got x-intercepts and y-intercepts wrong...instead of putting (6,0) (2,0) for x intercepts i put x=6, x=2😆

and i missed the y intercept alltogether😆

my teacher said if i get a bad grade she will let me retake another version....so i'll remember how you did the factoring😊

but i did really well on the rest of the test =D

Thanks again!
