Answer:
Hello,
Answer A
Step-by-step explanation:
if x=0 then sin(2*0)=sin(0)=0
if x= π/4 then sin(π/2)=1
if x= π/2 then sin(π)=0
X2+5x=0
7x+0
divide both sides by 7
7 divided by 0 is 0
x=0
0=0
Firstly, you have to isolate the X on one side if the equation by doing that you have to divide the numbers that are on the same side of the equation as part of the X.
