Q1. In the class we have learnt "Solving Quadratic Equations by Inspection, when coefficient a = 1" (for example, x2 – 11x + 10 = 0). Now your task is to do research on "Solving Quadratic Equations by Inspection, when coefficient a + 1" (for example, 4x2 – 12x + 9 = 0). Then, find 2 different quadratic equations and solve them step by step according to your research.
