Answer:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations.
ANSWER
1. No solution
2. 4 and 6
3. 81
EXPLANATION
1. The given quadratic equation is
This implies that:
There is no real number whose square is negative one.
This quadratic equation has no solution.
2. The given quadratic equation is
We split the middle term with -6,-4 because their product is 24 and their sum is -10
We factor by grouping
We have x=4 and x=6.
3. The given quadratic equation is
We the square of half the coefficient of x to both sides of the equation.
The correct choice is C.
The mathematical expression of the given complex number above is -5 + 4i. The conjugate of this complex number is that which has an opposite operation. The given is an addition operation. That is -5 - 4i. Therefore, the answer is the third among the choices.
