2x^2-15x-8

mathslover (mathslover):

\[\large{2x^2-15x-8}\] You have to factorize this?

OpenStudy (anonymous):

yes

mathslover (mathslover):

ok so : : \[\large{2x^2+16x-1x-8}\] \[\large{2x(x+8)-1(x+8)}\]

mathslover (mathslover):

try to take (x+8) common

OpenStudy (anonymous):

how do you do that??

OpenStudy (anonymous):

need help @Ganpat

OpenStudy (ganpat):

can u continue from wher mathslover stopped ??

OpenStudy (neo92):

wht z da step u dnt understnd?

OpenStudy (ganpat):

2x(x+8)−1(x+8) what common can u take from this ??

OpenStudy (ganpat):

@broderick365 : der ??

OpenStudy (anonymous):

8

OpenStudy (ganpat):

no no.. 2x(x+8)−1(x+8) (x+8) (2x -1).. x+8 .. should be common right ??

OpenStudy (neo92):

@broderick365 see what is the common term there. is it 8 or ??

OpenStudy (anonymous):

yehp

OpenStudy (ganpat):

i thought u understood in previous problem. .. :(

OpenStudy (anonymous):

not really

OpenStudy (ganpat):

ha ha, u shd have told me.. :D.. anyways.. now do u understand ??

OpenStudy (anonymous):

so the answer is 2x+1 x+8

OpenStudy (ganpat):

noo.. (x+8) (2x -1) = 0 equate each bracket to 0, and find x.. u will get 2 values..

OpenStudy (anonymous):

how do you do that??

OpenStudy (ganpat):

x+8 = 0 and 2x -1 = 0 now, can u simplify ??

OpenStudy (anonymous):

so the answer would be -8

OpenStudy (ganpat):

one answer is x = -8.. and other is x = 1/2..
