Question

What is the factored form of y = x2 − 4x + 3? y = (x − 4)(x − 1) y = (x − 3)(x − 1) y = (x − 2)(x − 2) y = (x + 1)(x + 3)

Answer 1

y = (x - 3)(x - 1)

Explanation:

To factor consider the factors of the constant term ( + 3) which sum to give the coefficient of the x- term ( - 4)

The factors are - 3 and - 1, hence

y = x² - 4x + 3 = (x - 3)(x - 1)

Answer 2

Y = ( x - 3 ) ( x - 1 )

Explanation:

Y = x ^ 2 - 4 x + 3

x ^ 2 - 3 x - x +3

x ( x -3 ) - 1 ( x - 3 )

( x - 3 ) ( x - 1 )

y = ( x - 3 ) ( x - 1 )
