Answer:
Step-by-step explanation:
we are given the polynomial as
here we can see that the GCF of 
, 
and 
is
Hence we take it outside the bracket
The polynomial within the bracket 
can not be factorized further , hence this would be our final answer.
Answer:
b=1/2
Step-by-step explanation:
2logb - 3logb = log8b - log4b
log
- log
= log8b - log4b
log(
) = log(2)
∴1/b = 2
∴b = 1/2
Answer:
±1, ±2, and ±4
Step-by-step explanation:
4x² + bx + c = (Ax + B) (Cx + D)
Distribute:
4x² + bx + c = ACx² + (AD + BC) x + BD
Matching the coefficients, AC = 4. So A must be a factor of 4. Possible values of A are therefore ±1, ±2, and ±4.
