Question

check whether (2×+1) (3×+1)=2(×-1)(×-2) is quadratic equalion or not?​

Answer 1

Answer:

$(2x + 1)(3x + 1) = 2(x - 1)(x - 2) \\ It \: \: is \: \: a \: \: Quadratic \: \: Equation$

Step-by-step explanation:

$(2x + 1)(3x + 1) = 2(x - 1)(x - 2) \\ 6 {x}^{2} + 2x + 3x + 1 = 2( {x}^{2} - 2x - x + 2) \\ 6 {x}^{2} + 5x + 1 = 2( {x}^{2} - 3x + 2) \\ 6 {x}^{2} + 5x + 1 = 2 {x}^{2} - 6x + 4 \\ 6 {x}^{2} - 2 {x}^{2} + 5x + 6x + 1 - 4 = 0 \\ \underline{ \underline{ 4 {x}^{2} + 11x - 3 = 0}}$
