Factors of -6 that add up to -1:
(x - 3)(x + 2)
Set them to 0 and solve for x
<span>x = 3 </span>
<span>x = -2</span>
2,180 - 150 • m
2,180- 150 • 6 =
2180- 900=m
1280=m
So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;
2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5
Hope this helps you. Any questions please ask.
