Factor 4x 2 + 12x + 5 . (2x + 5)(2x + 1)

swat32

$4x^2 + 12x + 5=4x^2+2x+10x+5 \\ \\ =2x(2x+1)+5(2x+1)=(2x+5)(2x+1) \\ \\ \therefore4x^2+12x+5=(2x+5)(2x+1)$

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
