OpenStudy (hhmorris98):

x=-6 and x=-4

OpenStudy (welshfella):

No direct answers please Read Code of Conduct.

OpenStudy (welshfella):

This function will factor into the form (x + a)(x + b) where a times b = + 24 and a + b = -10

OpenStudy (welshfella):

both answers given are incorrect

OpenStudy (moli007):

oh D;

OpenStudy (hhmorris98):

No you factor it out to (x-a)(x-b) because you are looking for a and b to add to -10 and to do so they must be negative.

OpenStudy (welshfella):

( x - 4)( x - 6) = 0 so x - 4 = 0 or x - 6 = 0 x = 4 or 6

OpenStudy (welshfella):

Sorry not D ITS C

OpenStudy (moli007):

so they dont turn negative?

OpenStudy (anonymous):

the right answer is c

OpenStudy (welshfella):

the factors contain negatives but the roots are positive because x - 4 = 0 or x - 6 = 0 solving these 2 equations gives you 4 and 6

OpenStudy (hhmorris98):

OpenStudy (anonymous):

x=4 or x=6

OpenStudy (hhmorris98):

postive 4 and postitive 6 don't make negative 10

OpenStudy (welshfella):

@hhmorris98 - the factoring is correct but the roots are not -4 or -6

OpenStudy (hhmorris98):

Okay I see now. Thank you sorry for that.

OpenStudy (moli007):

thank you for helping everyone :)
