Question

Simplily: { (2²_112+15) (x+2)} = (x²-4)​

Answer 1

Answer:

$(4 - 127)(x + 2) = ( {x}^{2} - 4) \\ \rightarrow (123)(x + 2) = ( {x}^{2} - 4) \: \: \\ \rightarrow \: 123x + 246 = {x}^{2} - 4 \: \: \: \: \: \\ \rightarrow \: {x}^{2} - 123x = - 4 - 246 \: \\ \rightarrow \: {x}^{2} - 123x = - 250$
