Question

3√2x square - 5x - √2 = 0 . Solve by factorisation and say roots.​

Answer 1

Answer:

Required zeroes of the given equation are √2 and - 1 / 3√2.

Step-by-step explanation:

Given quadratic equation : 3√2 x^2 - 5x - √2 = 0

Method 1

Using Quadratic Formula :

From the properties of quadratic equations, if an equation is ax^2 + bs + c = 0 then it's roots are :

\boxed{\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}}

2a

−b±

b

2

−4ac

On comparing the given equation with ax^2 + bx + c = 0, we get :

a = 3√2 ; b = - 5 ; c = - √2

Therefore,

= > x = [ - ( - 5 ) ± √{ ( - 5 )^2 - 4( 3√2 x - 2 ) } ] / ( 2 x 3√2 )

= > x = [ 5 ± √{ 25 + 24 } ] / ( 6√2 )

= > x = ( 5 ± √49 ) / 6√2

= > x = ( 5 ± 7 ) / 6√2

= > x = 12 / 6√2 Or - 2 / 6√2

= > x = √2 Or - 1 / 3√2
