x² + 5x - 6 can be expressed as (x + 6)(x - 1).
The missing numbers are 3, and 7
the pattern is +2 to each number
Step-by-step explanation:
5(tanx)^2 -2 +tanx=0
let tanx=y
5y^2 + y-2=0
y=0.5403 or y= -0.7403
tanx=0.5403
x=arctan(0.5403)
x=28.38°
or
tanx=-0.7403
x=arctan(-0.7403)
x=143.49°
-2(-2)+3=7
-2(0)+3=3
-2(4)+3=-5
