This is the concept of algebra, the solution of the given expression will be given as follows;
-5x+2x²=-6x
adding 5x on both sides we get
5x-5x+2x²=-6x+5x
2x²=-x
divide both sides by 2
(2x²)/2=-x/2
x²=-x/2
divide both sides by x
(x²)/x=-x/(2x)
x=-1/2
the answer is x=-1/2
Answer:
C
Step-by-step explanation:
If the parent function is function 
and 
then
- the graph of the function
is translated a units to the right graph of the parent function; - the graph of the function
is translated a units to the left graph of the parent function; - the graph of the function
is translated a units up graph of the parent function; - the graph of the function
is translated a units down graph of the parent function.
In your case, the grapgh of the function 
is translated 2 units up the graph of the function 
Commutative property of multiplication is two numbers being multiplied either way,example 1x2 = 2x1.
Answer:
henc X = 30°
Step-by-step explanation:
here is the proof
when X=30° then
sin2x = sin2×30
=sin 60°
= √3/2
or else,
putting value of X = 30° then
sin2x= 2sinxcosx
= 2×sin30°×cos30°
=2×1/2×√3/2
= 2√3/4
= √3/2
hence proved sin2x= √3/2.
