It looks like you're working on evaluating algebraic expressions. The "Homework" section asks to evaluate an expression, but the expression itself isn't fully visible. However, based on your previous work, it appears you were attempting to evaluate x^2 - 4y^2 + 2x + 15 (using 15 as you did in your substitution) with x=2 and y=3. Let's re-evaluate that expression. The value z=4 is not used in this particular expression. Step 1: Substitute the given values x=2 and y=3 into the expression. x^2 - 4y^2 + 2x + 15 (2)^2 - 4(3)^2 + 2(2) + 15 Step 2: Calculate the powers. 4 - 4(9) + 2(2) + 15 Step 3: Perform the multiplications. 4 - 36 + 4 + 15 Step 4: Perform additions and subtractions from left to right. (4 - 36) + 4 + 15 -32 + 4 + 15 (-32 + 4) + 15 -28 + 15 -13 The evaluated expression is: -13 Send me the next one 📸
