Question

2 - -एक्स एक्स एक्स स्क्वायर माइनस एक्स माइनस 4 ​

Answer 1

HELLO DEAR,

GIVEN:- x^2 -x-4

SOLUTION:- To solve this we have to use Shridhacharya rule.

by using shridhacharya rule

x=[ -b +-√{(b)^2 -4ac}]/ 2a

So,

X= [-(-1) +- √{(-1)^2-4(1)(-4)}]/2(1)

X= [1 +- √{1+16}] /2

X= [1+-√(17)] / 2

Therefore ,

X= [1 + √17 ] / 2

X= [1 - √17 ] / 2

I HOPE IT'S HELP YOU DEAR,

THANKS.
