Answer:
Alternative B is the correct answer.
Step-by-step explanation:
Re-arrange the quadratic equation to identify the values of a, b and c. From the equation, a=6, b=-5, c=-3. Apply the quadratic formula and replace the values of a,b and c
Answer:
Choice B is correct answer.
Step-by-step explanation:
We have given a quadratic equation.
5x = 6x²-3
6x²-3-5x = 0
6x²-5x-3 = 0
ax²+bx+c = 0 is general quadratic equation.
x =(-b±√b²-4ac) / 2a is quadratic formula to solve equation.
comparing general equation with given equation, we have
a = 6 , b = -5 and c = -3
Putting above values in formula, we have
x = (-(-5)±√(-5)²-4(6)(-3) ) / 2(6)
x = (5±√25+72) / 12
x = (5±√97) / 12 which is the answer.
