How do you solve 2 sin2-5 sin plus 2 equals 0?
2*sin^2(x) - 5*sin(x) + 2 = 0 is a quadratic equation in sin(x).therefore,{2*sin(x) - 1}*{sin(x) - 2)} = 0=> sin(x) = 1/2 or sin(x) = 2The second solution is rejected since sin(x) cannot exceed 1.The principal solution is x = arcsin(1/2) = pi/6 radians. Additional or alternative solutions will depend on the domain for x - which has not been given.
What are the solutions to the equation x2 plus 4x-9 equals x plus 1?

2
How many solutions does the following system have x plus y equals 3 and 2x plus y equals 5?
It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
How many solutions does x2-4x plus 4 equals 0 have?
It has two equal solutions of 2
Verify that sin minus cos plus 1 divided by sin plus cos subtract 1 equals sin plus 1 divided by cos?
[sin - cos + 1]/[sin + cos - 1] = [sin + 1]/cosiff [sin - cos + 1]*cos = [sin + 1]*[sin + cos - 1]iff sin*cos - cos^2 + cos = sin^2 + sin*cos - sin + sin + cos - 1iff -cos^2 = sin^2 - 11 = sin^2 + cos^2, which is true,
