Answer 2

Giving eq. -

2x² + x - 300 = 0

From comparing the standard form of

Quadratic equation ax² + bx + c = 0

Here , a = 2 , b = 1 , c = -300

Using Shridharacharya Formula :-

-b + √b² - 4ac

x = ---------------------

2a

-1 + √1 - 4(2)(-300)

x = -----------------------------

2(2)

-1 + √1 + 2400

x = -----------------------

4

-1 + √2401

x = ------------------

4

-1 + 49

x = ------------

4

So , x = 48/4 , -50/4

x = 12 , -25/2
