HELP PLS I GIVE BRAINLIST part 1. create 2 radical equations one that has an extraneous solution, and one that does not have an extraneous solution. use the equation below as a model. use a constant in place of each variable a, b,c, and d. you can use positive and negative constants in your equation.
a√(x+b) + c=d that has an extraneous solution
a√(x+b) + c=d that does not have an extraneous solution
part 2. show your work in solving the equation. include the work to check your solution and show that your solution is extraneous.
a√(x+b) + c=d that has an extraneous solution
a√(x+b) + c=d that does not have an extraneous solution
part 3. explain why the first equation has an extraneous solution and the second does not
PLS ANSWER ASAP THANKS

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
