What are the factors of x2 + 11x + 24?
(x − 6)(x − 4)
(x + 6)(x + 4)
(x − 3)(x − 8)
(x + 3)(x + 8)

can u explain ?
OpenStudy (e.cociuba):
My bad hun, it's C.)
x^2 - 11x + 24 { x^2 means x squared }
= x^2 - 8x - 3x + 24............{ Since, 24 = (- 8) x (- 3) and - 11x = - 8x - 3x }
= x (x - 8) - 3 (x - 8)
= (x - 3)(x - 8)

Wat do ya'll say @skullpatrol

how about this one =
What are the factors of 3x2 + 10x + 3?
(3x − 1)(x − 3)
(3x − 3)(x − 1)
(3x + 1)(x + 3)
(3x + 3)(x + 1)
OpenStudy (e.cociuba):
x+3 and 3x+1 are both factors of the polynomial given.
So, it's C.)
OpenStudy (e.cociuba):
3x^2+10^x+3
=3x^2+9x+x+3[by middle term factorization method]
=3x(x+3)+(x+3)
=(x+3)(3x+1)
U can use F.O.I.L as proof.....

FOIL is what I showed you on the last question.
OpenStudy (e.cociuba):
