+3 + 3x2 – 2x-6
is this a prime polynomial

see explanation

Step-by-step explanation:

This is not a prime polynomial as it can be factored into polynomials of lower degree.

Given

x³ + 3x² - 2x - 6 ( factor the first/second and third/fourth terms )

= x²(x + 3) - 2(x + 3) ← factor out (x + 3) from each term

= (x + 3)(x² - 2) ←can be reduced further as a difference of squares

= (x + 3)(x - )(x + )

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

well what did you do it matters what you did : )
