Proving Equivalent Expressions WORKSHEET
Suitable for Grades: Algebra I, IM 1
CCSS: HSA.APR.A.1, HSA.SSE.B.3
CCSS Description: Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.
Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.★ a. Factor a quadratic expression to reveal the zeros of the function it defines. b. Complete the square in a quadratic expression to reveal the maximum or minimum value of the function it defines. c. Use the properties of exponents to transform expressions for exponential functions. For example the expression 1.15t can be rewritten as (1.151/12)12t ≈ 1.01212t to reveal the approximate equivalent monthly interest rate if the annual rate is 15%

Proving Equivalent Expressions WORKSHEET DESCRIPTION
This nice worksheet gives learners an opportunity to consolidate their understanding of equations and identities. Learners need to place either an equal sign or the equivalence symbol in the box for each statement. Where the statement is an equation, learners need to solve the equation.
