Given:

The equation is:

x^2-64=0

One solutions is 8.

To find:

The other solution of the given equation.

Solution:

We have,

x^2-64=0

It can be written as:

x^2-8^2=0

(x-8)(x+8)=0              [\because a^2-b^2=(a-b)(a+b)]

Using zero product property, we get

x-8=0 and x+8=0

x=8 and x=-8

It is given that the one solutions is 8.

Therefore, the other solution is -8.

Answer:

3x³ + x² + x + 1

= 3x³ - 3x² + 4x² - 4x + 5x - 5 + 6

= 3x²(x - 1) + 4x(x - 1) + 5(x - 1) + 6

= (x - 1)(3x² + 4x + 5) + 6

but 3x³ + x² + x + 1 = (x - 1).Q(x) + R

=> Q(x) = 3x² + 4x + 5

R = 6
