x = √(14-4y-4) \\x=√(14-4y-) \\4, y \leq (7)/(2)

Step-by-step explanation: steps using the quadratic formula

all equations of form a
x^(2) + bx + c= 0 can be solved using the quadratic formula: The quadratic formula gives two solutions, one when ± is addition and when it is subtraction. This will take for ever to explain but I think u get the point
