Solve 6y2-5y-6 = 0 using the quadratic formula.A) y=- 3 over 2 or y =2 over 3B) Y = -5 or y = -6C) y or y=-2D) y = 2 or y = 3
Accepted Solution
A:
Answer:Ay=3 over 2 or y=-2 over 3Step-by-step explanation:the quadratic formula: y={-b±√(b²-4ac)}/2aIn the equation 6y²-5y-6= 0, a=6, b=-5, c= -6Substituting for the values in the formula we get:{-(-5)±√[(-5²)-4(6)(-6)}/2(6){5±√169}12={5±13}/12 (5+13)/12=3/2 or (5-13)/12= -2/3
