Question

A board of length (6x4 + 9x2- 21) meters is to be cut into three pieces of the same length. Find the length of each

Answer 1

Answer:

(2x⁴ + 3x² -7)

Step-by-step explanation:

Length is

• (6x⁴ + 9x²- 21)

It is to be divided by 3.

Note when dividing the polynomial by any value each of the terms is divides by same value:

• (6x⁴ + 9x²- 21)/3 =
• 6x⁴/3 + 9x²/3 - 21/3 =
• 2x⁴ + 3x² -7

Each piece is (2x⁴ + 3x² -7) meters long
