Answer:
(x -3)(x + 6)
Step-by-step explanation:
x^2+ 3x – 18
As you know
- 18 = -3 * 6
3 = -3 + 6
So
x^2+ 3x – 18
= (x -3)(x + 6)
2x - 2y = 12
-2x - 3y = -22
solution could be (x,2)
===============
2x - 6y = 10
x + 8y = 5
solution could be : (5,y)
==============
3x - y = -5
x + 4y = 7
solution could be : (x,2)
=============
x + y = 2
2x + y = 13
solution could be : neither....is this one written correctly ?
