For the polynomial x2 + 10x + 25,
a =
b = .

The values are a=1 b=10 c=25 and solving the expression we get x=-5

Explanation:

Given equation;

Solution:

The above equation can be written as

This equation is in the form of

is the general quadratic equation.

Comparing the above equation we get  

A=1, B=10 and C=25

To find value of “x” we use the formula as  

=

Substitute the values of a, b and c in the above equation we get

=

=

=

=

=-5

Results:

Thus the values are A=1, B=10, C=25 and X=-5

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
