Question

2x^2+12x+k
k>0
Find all values of "k" so that the trinomial can be factored as two binomials using integers? show work.

Answer 1

use the quadratic formula
x = (-b + sqrt(b^2 -4ac))/2a

Answer 2

i dont know the quadratic formula we dont learn that til next year

Answer 3

as -b/2a is an integer
we just hv 2 find k for which the other part is an integer
sqrt (144-8k)/ 4 = Integer

Answer 4

uh-oh

Answer 5

?? i dont know what any of that means
