15x^2 - 25 answer with a complete sentence
zubka84 [21]

Answer:

No, the following expression is not a difference of squares. Binomial can not be factored as the  difference of two perfect squares. 3 is not a square.

Step-by-step explanation:

Factor

15x^2 - 25

(15x)^2(-5)^5

Divide by 3 and factor

5(3x^2-5)

"Theory:

A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression."

What is the positive angle less than 2π that is coterminal with 14π/6
Dahasolnce [82]

Coterminal angles are angles that are made by the positive x-axis of the coordinate plane. The positive angle that is less than 2π and is coterminal with 14π/6 is  1/3π.

<h3>What are coterminal angles?</h3>

Coterminal angles are angles that are made by the positive x-axis of the coordinate plane.

The angle that 14π/6 makes from the positive x-axis is 1/3π, which is equal to 60°.

Hence, the positive angle that is less than 2π and is coterminal with 14π/6 is  1/3π.
