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

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

351°f
