Question

x(2x+1)(x-2)(2x-3)=63​

Answer 1

Answer:

$x(2x + 1)(x - 2)(2x - 3) = 63 \\ (2 {x}^{2} + x)(x - 2)(2x - 3) \\ (2 {x}^{2}(x - 2) + x(x - 2))(2x - 3) \\ (2 {x}^{3} - 4 {x}^{2} + {x}^{2} - 2x)(2x - 3) \\ 4 {x}^{4} - 6 {x}^{3} - 8 {x}^{3} + 12 {x}^{2} + 2 {x}^{3} - 3 {x}^{2} - 4 {x}^{2} + 6x \\ 4 {x}^{4} - 12 {x}^{3} + 5 {x}^{2} + 6x$
