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:
(0,-9)
Step-by-step explanation:
Well first we need to solve the rowing eqation by combining like terms and separating x.

So let’s do -3x
-9 = x -9
+9
x = 0.
So if x is 0 we can plug that in one of the equations.
y = 4(0) - 9
y = -9
So the solution where the 2 lines meet is at (0,-9)

Answer:
The answer is -8x-10
Step-by-step explanation:
-4(2x+3)-2
you will use the -4 to open the bracket
-8x-12-2
-8x-10
