Answer:
m=-1/4
Step-by-step explanation:
Answer:

Step-by-step explanation:
The quadratic can be solved in a straightforward way:

This tells you that the solutions are ...
2i or -2i
__
For each root of "a", (x -a) is a factor. Thus the factors of the equation are ...
(x +2i)(x -2i)
Answer:
(4 + x) * 2
Step-by-step explanation:
twice the sum means the total will be multiplied by 2 and sum is addition. So 4 and a number (x).
Step-by-step explanation:
Find the product, sum and factors which are P=56, S=15 and F=8,7 respectively.
r²+15r+56=0
replacing with the factors in the equation
=> r²+8r+7r+56=0
r(r+8)+7(r+8)=0
(r+8)(r+7)=0
=> r= –8 and –7
