For this case we must simplify the following expression:

(2x ^ 3 + 6x-1) + (3x ^ 2-7x)

We eliminate the parentheses taking into account that:

+ * + = +\\+ * - = -

So, we have:

2x ^ 3 + 6x-1 + 3x ^ 2-7x =

We add similar terms taking into account that:

Different signs are subtracted and the sign of the major is placed:

2x ^ 3 + 3x^2-x-1

Answer:

2x ^ 3 + 3x^2-x-1

What is the length of the radius of a circle with a center at 2 – i and a point on the circle at 8 + 7i?
AlladinOne [14]
We need to find a distance between this to points.
D=√((x2-x1)²+(y2-y1)²)

For complex plain, the real part of the complex number plays a role of x,
and  number of an imaginary part plays a role of y.
So,
D=√((8-2)² +(7+1)²)√ = √(36+64)=√(100)=10
Answer is D.10
