Question

how to simplify (can I factor?): x^2-5x+4=0

Answer 1

The sum of 2 numbers is -5 ? and the result of multiplying them is 4
-4 * -1

so (x - 4) * ( x - 1)

to check , multiply -1 * x = -x
, -4 * x = -4x
sum them = -5x ( as the middle )

Answer 2

I factored and got x=4,1

Answer 3

so: (x-4)(x-1) is the factored form?

Answer 4

thank you that makes sense!!

Answer 5

The factored form is (x-4)(x-1), the roots of the equation is x = 1, x = 4 .
