Analyzing Student Work
Analyze Marika's steps. Which statement is true about
her work?
Marika solved the equation (6x +15)2 + 24 = 0. Her work
is below.
1. (6x + 15)2 = -24
2. V6x +15)2 = -24
In step 2, Marika should have simplified / -24 to be
4-6
3. 6x + 15 = -25
4. 6x = -2.5 - 15
-256-15
5. X=
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 -24 = +25.
Marika correctly solved this equation.
