Find the roots of 3x2 – 7x – 6 = 0 by using quadratic formula.​

Answer 1

Answer:

x=-2/3 & x=2

Step-by-step explanation:

3x²-7x-6=0

3x²-9x+2x-6=0

3x(x-3)+2(x-3)=0

x-3=0 & 3x+2=0

x=3 & x=-2/3

and by

• 2nd metod

∆=[-b±√(b²-4ac)]/2a

=[7±√(49+72)]/6

=7±√121/6

=(7±11)/6

so,

7+11/6 7-11/6

=18/6 = -4/6
