Question

find the zeros of the function y=x^2-4x+3 by factoring

Answer 1

x²-4x+3 = (x - ?)(x - ?)

Answer 2

(x-3)(x-1)

Answer 3

Excellent. Now find zero. Do you know how to?

Answer 4

i have no idea

Answer 5

(x-3)(x-1) = 0 so either (x - 3) or (x - 1) must be equal zero.

Answer 6

(x-3)

Answer 7

or (x - 1).
So set both terms equal to zero.

(x - 3) = 0
(x - 1) = 0

Find x. You will have two answers.

Answer 8

x=3
x=1

Answer 9
