Solve: x2 – 26x + 48 = 0

OpenStudy (anonymous):

quadratic formula? complete the square? factor? probably factor is easiest

OpenStudy (anonymous):

i dnt understand how to do it

OpenStudy (anonymous):

two numbers whose product is 48 and whose sum is -26

OpenStudy (anonymous):

x1=24, x2=2 by factorisation

OpenStudy (anonymous):

you are going to write \[(x-a)(x-b)=0\] and you know that \[ab=48\] and \[a+b=26\]

OpenStudy (anonymous):

that if you can find those two numbers you win. not too hard in this case

OpenStudy (anonymous):

thanks
