So discriminant gives us 3 possibilites connected with result of the equation b^2-4ac. If it is bigger than zero, there are 2 solutions, if answer is exactly 0, then there is one answer and if the number is lower than 0, there are no solutions.
Discriminant of your quadratic equation is (-4)^2-4*1*5=16-20=-4, so there are no solutions.
Equation = 12 - -24 = ?
After keep, change, flip: 12 + 24 = ?
Answer = 36
Answer:
True
Step-by-step explanation:
The midpoint is the average of the values:
