To factor a quadratic of the form ax^2+bx+c you need to find two values, j and k, which satisfy two conditions...
jk=ac=12 and j+k=b=8, so j and k must be 2 and 6
Then the factors are just (a+j)(a+k), in this case:
(a+2)(a+6)
So the missing term was 6
Answer:
Step-by-step explanation:
- (3/4x + 2) - (1/4x + 5) =
- 3/4x - 1/4x + 2 - 5 =
- 2/4x - 3 =
- 1/2x - 3
Correct choice is D
