Step-by-step explanation:
Given the question :
Jane evaluates x squared minus 3 x + 5 for x = negative 2 below. Step 1: (negative 2) squared minus 3 (negative 2) + 5 Step 2: Equals negative 4 + 6 + 5 Step 3: Equals 7 What, if any, was Jane's mistake?
Jane's evaluation :
x² - 3x + 5 for x = - 2
Step 1:
(-2)² - 3(-2) + 5
Step 2:
-4 + 6 + 5
Step 3 :
= 7
Jane's mistake was in STEP2,
evaluating (-2)² = 4 and not - 4
Hence, (-2)² - 3(-2) + 5
= 4 + 6 + 5
= 15
