You would need to facto 2x² + 9x - 35 to get (2x - 5)(x + 7).
We can find this first by dividing the 2x² into 2x and x, which we can put into the brackets:
(2x _ _)(x _ _)
Then we need to find two factors of -35 that have a difference of 9 when one is multiplied by 2, which gives us +7 and -5 as (7 × 2) - 5 = 14 - 5 = 9.
This gives our final answer as:
(2x - 5)(x + 7)
We cannot use foil on this expression as there are no brackets to expand.
I hope this helps!
Answer:
The three coplannar points are
Points A, B & D in Plane O
Or
Points A, B & C in Plane P.
Step-by-step explanation:
All the angles in a triangle equal 180 degrees so 128 + (5x+10) + 9x = 180
Group the like values to get 138 + 14x = 180
Subtract 138 from 180 to get 14x = 42
Divide 42 by 14 to get x = 3
Therefore x = 3
