Question

simplify 3m square÷m 2m 4square ÷m square​

Answer 1

Answer:

The quadratic formula for the standard Quadratic equation of the form :

ax

2

+bx+c=0 is :

x=

2a

−b±

b

2

−4ac

Now Comparing the given equation 3m

2

+2m−7=0 to the standard form we get:

a=3,

b=2 and

c=−7

Substituting value of a,b and c in the quadratic formula we get:

x=

2×3

−2±

2

2

−4×3×(−7)

⇒x=

6

−2±

88

⇒x=

2×3

2×(−1±

)

∴ x=

2

(−1+
