Question1. Circle all of the following polynomials that are DEGREE 2: [1 mark]
Studdy Solution
STEP 1
1. A polynomial of degree 2 is a quadratic polynomial, which has the highest power of as 2.
2. We need to identify which of the given expressions are quadratic polynomials.
STEP 2
1. Analyze each polynomial to determine its degree.
2. Circle the polynomials that are of degree 2.
STEP 3
Analyze the polynomial :
- The highest power of is 1.
- Therefore, it is not a degree 2 polynomial.
STEP 4
Analyze the polynomial :
- The highest power of is 2.
- Therefore, it is a degree 2 polynomial.
STEP 5
Analyze the polynomial :
- Expand the expression:
- The highest power of is 2.
- Therefore, it is a degree 2 polynomial.
STEP 6
Analyze the polynomial :
- Expand the expression:
- The highest power of is 2.
- Therefore, it is a degree 2 polynomial.
STEP 7
Circle the polynomials that are of degree 2:
-
-
-
The polynomials that are degree 2 are:
