STEP 1: REPLACE P(X) WITH P(-X)
Step 2: Change the Signs!
Step 3: Identify the Number of Sign Changes
Problem 5: According to Descartes's Rule of Signs, Identify how many negative real roots there are.
Step 6: Graph the orginal equation to find the negative real roots.
The graph shows that the equation contains only one real negative root at (-1, 0). The only real negative root is -1.
Step 1: Create a Brace Map
Step 2: Identify the Formula and Substitute the Correct Values
Step 3: Graph to Solve
Although there are two x-intercepts, one is a negative and cannot be used to solve the equation. The other x-intercept, located at (5,0) can be used to solve the equation.
Step 5: Substitute the number found by graphing to solve.
The dimensions of the garden are the height=5, the smaller base=10, and the larger base=14
