Answer:
2x^2 -x +1 = 0
Step-by-step explanation:
For roots α and β, the original equation can be factored as ...
f(x) = 2(x -α)(x -β)
If we add 1 to each of those roots, the factors become ...
g(x) = 2(x -(α+1))(x -(β+1))
This can be rearranged to be ...
g(x) = 2((x -1) -α)((x -1) -β)
That is, we can get the desired equation by replacing x with x-1, effectively shifting the function right one unit.
2(x -1)² +3(x -1) +2 = 0
2x^2 -x +1 = 0
Well get a protractor I don't know for sure. it
2(a+3)+3(2a-1)
=2a+6+6a-3
=8a+3
Answer:
the first one is
+2 +4 + 8 + 16 +32
he multiply by 2 every time he add numbers so its 65
the second one he make this
-8 -4 -2 -1
every time he Take from numbers he devide by 2
so its 5
the third one
+6 +18 + 54 + 162
every time he add he multiply by 3
ao its 162 +80 =242
the fourth one is
+33 +66 + 132 +264
he multiply by 2 every time he add
so its 267+264=531
the fiveth one is
he put the roots
2²,3²,4²,5²,6²
so the answer is 36
Step-by-step explanation:
A 65
B 5
C 242
D 531
E 36
hopefully its helpful man
Answer:
x = - 7
Step-by-step explanation:
Given
- 5(x - 2) - (x + 2) = 50 ← distribute parenthesis on left side
- 5x + 10 - x - 2 = 50, that is
- 6x + 8 = 50 ( subtract 8 from both sides )
- 6x = 42 ( divide both sides by - 6 )
x = - 7
