Question

solve the equationx^4-11x^2+2x+12=0 √5-1 is a root​

Answer 1

Answer:

x= root5 -1 ,-root5 -1, -1 ,3

Step-by-step explanation:

x=root5 -1

squaring on both sides

x^2 +2^x-4 =0

divide it by x^4-11x^2+2x+12=0

ans.= x^2-2x-3=0

x= -1, 3

Answer 2

Given:

√5-1  are the roots

Explanation:

x =√5 -1 , -root -1,-1,3

x=√5 -1

squaring both the side we will get sides

x² +x²- 4 =0

Divide this by (x⁴-11x²+2x+12 = 0)

                             x²-2x-3 = 0

x= 3,-1

Therefore answer to this question = 3,-1
