Activity 1.1: NOW IT’S YOUR TURN! A. Instructions: Tell whether the equation is quadratic or not. Justify your answers. 1. 2 + 5 − 4 = 0 4. 4( − 3) + 5 = 3 − 2 2. 3 − 8 = 2 5. 26 = 3−2 3. + 2 = 5− B. Write the following in standard form 2 + + = 0 and identify a, b and c. 1. 15 − 22 = 3 4. 5 − ( + 3) = 42 2. 3 − 42 = 8 5. 2 − 3( + 4) = −2 3. ( + 2)2 = 2 − 1​
