Multiplying Polynomials
Answer:
Polynomial 1:
- Simplified Form: 6x^2 - x - 1
- Name by Number of Terms: trinomial
Polynomial 2:
- Name by Number of Terms: binomial
Polynomial 3:
Step-by-step explanation:
Polynomial 1:



It has 3 terms, so it's a <u>trinomial</u>.
Polynomial 2:
There is one term with x and x is raised to the first degree, so it's <u>linear</u>.
There are 2 terms, so it's a <u>binomial</u>.
Polynomial 3:




Since there are no variables and the answer is just 2, it's a <u>constant</u>.
Note: I took a test on this and it seemed to be all correct
Combine like terms. -9x^4+6x^3+x^2+6x
Multiply 8cm by 4cm.
( 8 x 4 = ? )
8 x 4 = 32 because ( 8, 16, 24, 32)
Half it. Which then gives you 16.
=16
