Question

x(3x + 1 /2)= 6.
Solve the following using quadratic formula ​

Answer 1

Answer:

4/3 , -1.5

Step-by-step explanation:

x(3x+1/2or0.5)=6

3x²+0.5x-6=0

find root by formula

ax²+bx+c=0

a not equal to 0

here a=3 b=0.5 c=-6

formula = (-b+/- root under (b²-4ac))/2a

(-0.5+/- root under (0.5²-4×3×-6))/2×3

solve

first root (-0.5+root under(0.25-(-72)))/6

(-0.5+root under (72.25) )/6

(-0.5+8.5)/6

8/6 =4/3

second root (-0.5-8.5)/6=-1.5
