Storing Strategies

Evaluate f(x)=-2x²+ 1 for f(-3)

-3→X Then type in -2X²+1

Find the value of x²+3x-2 when x=4

4→X Type X²+3X-2 into the calculator

Solve for x: 2(-x - 4) = 4x + 16

Store the possible solutions for X then test each one with 2(-x - 4) = 4x + 16 to see which one makes the equation true (1)

Which expression is equivalent to (5x²y³)/(10xy)

We choose what to store 5→X 10→Y Type in (5x²y³)/(10xy) then test the possible answers to find the same value

Which expression is equivalent to √(42n⁹) in simplest radical form?

We get to choose what to store 5→N Type in √(42n⁹), then test ALL of the possible solutions for the same value If more than one solution is the same, pick the one which has the SMALLEST numbers and variables under the √ as this will be the SIMPLEST form of the expression

Simplify (3x²y⁴)²(-4xy⁵)

We get to choose what to store 5→X 10→Y Then enter the expression (3x²y⁴)²(-4xy⁵) and test each possible solution for the one that has the same value

Factor x²+12x+35

We get to choose what to store 5→X Type in x²+12x+35, then test each of the possible solutions for the same value
