Question

3q2=2q+8 use qaudratic formula and solve​

Answer 1

Answer:

Step-by-step explanation:

Sol. 3q2 = 2q + 8

3q2 – 2q – 8 = 0

Comparing with aq2 + bq + c = 0 we have a = 3, b = – 2, c = – 8

b2 – 4ac = (– 2)2 – 4 (3) (– 8)

= 4 + 96

= 100

By Formula method,

q

=

-  b ± √(b2 – 4ac)

2a

∴ q

=

-(-2) ± √100

2(3)

∴ q

=

2 ±10

6

∴ q

=

2  ± 10

6

∴ q

=

2 + 10

or

2 – 10

6

6

∴ q

=

12

or

-8

6

6

∴ q

=

2

or

-4/3
