Question

x^2-7ix-12= 0. solve by method of factorization​

Answer 1

Answer:

${x}^{2} - 7ix - 12 = 0 \\ {x }^{2} - 4ix - 3ix - 12 = 0 \\ {x }^{2} - 4ix \: - 3ix + 12 {i}^{2} = 0 \\ x(x - 4i) - 3i(x - 4i) = 0 \\ (x - 3i)(x - 4i) = 0 \\ x = 3i \: \: \: or \: x = 4i\: </p><p> \\ = = = = = = = = = = =$
