Simplify polynomial

3jsquared - jsquaredk - 6 - 4jsquaredk - 2jsquared + 4

sorry it didn't allow me to put the little two on top so i had to say squared

j² - 5j²k - 2

Step-by-step explanation:

3j² - j²k - 6 - 4j²k - 2j² + 4

To simplify this polynomial, we can collect like terms. A term is number (s) or variable (s) that are grouped together by multiplication. Like terms have the same variable and exponent.

We have three groups of like terms:

The j-squares (j²), the j-squared k (j²k) and the constants (no variable).

Remember to include the negatives!

The j-squares are: 3j²; - 2j²

The j-squares k are: - j²k; - 4j²k

The constants are: - 6; 4

Simplify:

3j² - j²k - 6 - 4j²k - 2j² + 4

Rearrange the polynomial by like terms

= ( - j²k - 4j²k) + (3j² - 2j²) + ( - 6 + 4)

Add or subtract the like terms

= (-5j²k) + (j²) + (-2)

Remove brackets and rearrange so the negative is not first

= j² + - 5j²k + - 2

Simplify where two signs are together. Adding a negative is subtraction.

= j² - 5j²k - 2 Simplified
