Marika solved the equation (6x + 15)2 + 24 = 0. her work is below. 1. (6x + 15)2 = –24 2. startroot (6 + 15) squared endroot = startroot negative 24 endroot 3. 6x + 15 = negative 2 startroot 6 endroot 4. 6x = negative 2 startroot 6 endroot – 15 5. x = startfraction negative 2 startroot 6 endroot minus 15 over 6 endfraction analyze marika’s steps. which statement is true about her work? in step 2, marika should have simplified startroot negative 24 endroot to be 4 startroot negative 6 endroot. there are no real solutions to this equation because the square root of a negative number is not a real number. there should be two real solutions to this equation because startroot negative 24 endroot = plus or minus 2 startroot 6 endroot. marika correctly solved this equation.
