Answer:

(2a+3 ) (a-4 )=0

Step-by-step explanation:

2a^2 + 8a - 15 = 3a - 3

Subtract 3a from each side

2a^2 + 8a-3a - 15 = 3a-3a - 3

2a^2 + 5a - 15 =  - 3

Add 3 to each side

2a^2 + 5a - 15+3 = 3 - 3

2a^2 -5a -12=0

(2a+3 ) (a-4 )=0  These are the factors

Let a = 0.9876 and b = 0.9887 with N = 2, calculate the midpoint.
rodikova [14]

Answer:

For a=0.9876 and b=0.9887 mid point will be 0.98815

Step-by-step explanation:

We have given a = 0.9876 and b = 0.9887

And N = 2

We have to find the mid point

For finding mid point we know that formula

Midpoint =\frac{a+b}{2} , here we have given a=0.9876 and b = 0.9887

So midpoint will be =\frac{0.9876+0.9887}{2}=\frac{1.9763}{2}=0.98815

So for a=0.9876 and b=0.9887 mid point will be 0.98815
