Question

solve for x- 6x^2-5x-6=0 by quadratic meathod​

Answer 1

Answer: Use the quadratic formula to find the solutions.

− b ± √ b ^2 − 4 ( a c )/2 a

Substitute the values  

a = 6 ,  b = 5 , and  c =− 6  into the quadratic formula and solve for  x .

− 5 ± √ 5^ 2 − 4 ⋅ ( 6 ⋅ − 6 ) /2 ⋅ 6

Step-by-step explanation:

x = − 5 ± √ 25 + 144 /2 ⋅ 6

Add  25  and  144 .

x =  − 5 ± √ 169 /2 ⋅ 6

Multiply  2  by  6 .

x =  − 5 ± 13  /12

The final answer is the combination of both solutions.

x =  2 /3 ,  − 3 /2

Answer 2

answer: There are two values of x: 7/3 and -2/3
