Will fan metal and give testimony!!!!!!! Solve. x2 – 5x + 6 = 0 A. {5, –1} B. {3, –2} C. {–2, –3} D. {2, 3}

OpenStudy (imsleeziboii):

Okay so here is what you do

OpenStudy (imsleeziboii):

You need to input those coordinates in and see which one equals 0

OpenStudy (imsleeziboii):

Lets do the first one

OpenStudy (imsleeziboii):

5^2=25

OpenStudy (anonymous):

what two numbers multiply together give you 6 and together give you -5?

OpenStudy (imsleeziboii):

3 and 2

OpenStudy (imsleeziboii):

THE answer is D

OpenStudy (anonymous):

would you mind explaining?

OpenStudy (imsleeziboii):

factorization

OpenStudy (imsleeziboii):

That is a quadratic equation

OpenStudy (anonymous):

right

OpenStudy (anonymous):

C WILL GIVE U THAT :D

OpenStudy (imsleeziboii):

Tell him the work, i was never good at quadratics

OpenStudy (anonymous):

Im kinda confused... I have 2 human calculators giving me different answers

OpenStudy (imsleeziboii):

lol

OpenStudy (imsleeziboii):

You just input the coordinates to get 0

OpenStudy (sand-lock53):

seperate x from the rest

OpenStudy (imsleeziboii):

You put the coordinates in the x value

OpenStudy (imsleeziboii):

\[ax^2+bx+c=0\]

OpenStudy (anonymous):

Bruh i just told you.. "what two numbers multiply together give you 6 and together give you -5?"

OpenStudy (anonymous):

add together give -5

OpenStudy (anonymous):

-2,-3

OpenStudy (imsleeziboii):

Right.

OpenStudy (anonymous):

thas all u need

OpenStudy (imsleeziboii):

its just simple quadratics

OpenStudy (anonymous):

alright thanks guys

OpenStudy (imsleeziboii):

Im doing this right now in my school. It is a pain in the a** if it isnt factorable

OpenStudy (imsleeziboii):

and most quadratics arent

OpenStudy (anonymous):

um... one of you gets the medal and the other the fan and testimony

OpenStudy (sand-lock53):

goodness watch youtr language

OpenStudy (imsleeziboii):

lol

OpenStudy (imsleeziboii):

give him the medal and fan
