solve below to find x intercepts \(\large 0 = x^2-6x+5\)

ganeshie8 (ganeshie8):

you may factor it and solve

OpenStudy (vshiroky):

I don't understand exactly what that means still

ganeshie8 (ganeshie8):

do u knw how to factor a quadratic ?

ganeshie8 (ganeshie8):

first, find any two numbers such that : 1) they add up to -6 2) they multiply to 5

OpenStudy (vshiroky):

-1-5

ganeshie8 (ganeshie8):

Excellent ! -1 and -5 are ur magic numbers

ganeshie8 (ganeshie8):

\(\large 0 = x^2-6x+5 \) factors to \(\large 0 = (x-1)(x-5) \)

ganeshie8 (ganeshie8):

that gives \(\large 0 = x-1 \\ ~or~~ 0 = x-5 \)

ganeshie8 (ganeshie8):

\(\large x = 1\) \(\large x = 5\)

ganeshie8 (ganeshie8):

^^those are ur x intercepts

ganeshie8 (ganeshie8):

the ordered pairs wud be : \(\large (1, 0)\) \(\large (5, 0)\)

OpenStudy (vshiroky):

Ahhhhh that makes sense. Thank you. I didn't understand how it was explained on the site.
