What is a degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the polynomial.

What are like terms in a polynomial?

Back

Like terms are terms that have the same variable raised to the same power, which can be combined by adding or subtracting their coefficients.

What is the result of multiplying (x + a)(x + b)?

Back

The result is x^2 + (a + b)x + ab, which is derived using the distributive property or FOIL method.

How do you simplify the expression (k + 4)(5k - 1)?

Back

Using the distributive property: k*5k + k*(-1) + 4*5k + 4*(-1) = 5k^2 + 19k - 4.
