Answer:
Cubic Expression
Step-by-step explanation:
5x + 3x² − 7x³ + 2
-7x³ + 3x² + 5x + 2
Highest power/ degree of the polynomial is 3, so it's cubic
The Correct answer for the expression 5x + 3x² − 7x³ + 2 is Cubic expression.
A cubic expression is one variable in an equation of the form ax³ + bx² + cx + d = 0 , where the coefficients are a, b, and c, and the constant is d.
Now the given expression is
5x + 3x² − 7x³ + 2
Rearranging the expression,we get
− 7x³ + 3x² + 5x + 2
Now since the highest power in the expression is 3, therefore it is a cubic expression of the form ax³ + bx² + cx + d.
