POST TEST ON A-APR 1 AND A-APR 3

Front

What is a solution to a function?

Back

A solution to a function is a value of the variable that makes the function true. For example, if f(x) = 0, then x is a solution if substituting x into the function results in 0.

Front

What is the product of the polynomials (3x + 4) and (-x^2 + 2x - 8)?

Back

Front

How do you simplify the expression 30 ÷ (x + 3)?

Back

This expression is already in its simplest form, representing the division of 30 by the sum of x and 3.

Front

What is the equivalent expression for (x - 7)(x^2 - 5x + 3)?

Back

Front

What is the simplified form of the polynomial expression -4x^2(x - y^2) + (y^2 + 4) - 2y^2(x^2 - 6y) + 7x^2?

Back

The simplified form is 3x^3 + 2x^2y^2 + 13y^3 + 4.

Front

What is a polynomial?

Back

A polynomial is a mathematical expression consisting of variables, coefficients, and non-negative integer exponents, combined using addition, subtraction, and multiplication.

Front

What does it mean for an expression to be equivalent?

Back

Two expressions are equivalent if they have the same value for all values of the variable(s) involved.

Front

What is the degree of a polynomial?

Back

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

Front

What is the difference between a monomial and a polynomial?

Back

A monomial is a single term, while a polynomial is a sum of two or more monomials.

Front

What is the process of factoring a polynomial?

Back

Factoring a polynomial involves rewriting it as a product of its factors, which can be simpler expressions.
