Step-by-step explanation:
Answer: here a, b, and c are real numbers and a≠0. A solution to such an equation is called a root. Quadratic equations can have two real solutions, one real solution, or no real solution. If the quadratic expression on the left factors, then we can solve it by factoring. A review of the steps used to solve by the factory..

Answer:
A=-2; B=-1
Step-by-step explanation:
3a - 2b + 4 =0
2a -5b -1 = 0
Let's multiple the top equation by 2, and the bottom by -3, and then use addition.
[3a - 2b + 4 =0]*2
[2a -5b -1 = 0]*(-3)
6a-4b+8=0
-6a+15b+3=0
Now add the two equations together:
11b + 11 = 0
Subtract 11 from both sides
11b = -11
Divide both sides by 11
b=-1
Substitute in the first equation:
3a - 2(-1) + 4 = 0
Simplify to get 3a+6 = 0
Subtract 6 from both sides to get 3a = -6
Divide both sides by 3 to get a=-2
