what is the general solution to the equation?

2 cos^2 x - 5 cos x - 3 = 0

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.

What is the solution to the division problem below x3+x2-11x+4/x+4

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2
