Question

3x4+6x3-2x2-10x-5 के अन्य सभी शून्यक ghayat कीजिए यदि इसके दो शून्यक root 5\3 और -root 5\3हैं

Answer 1

Answer:

${3x}^4 + {6x}^3 - {2x}^2 - {10x} -5 =0$

putting the values √5/3 and -√5/3 in place of x

${3x}^4 + {6x}^3 - {2x}^2 - {10x} -5 =0$

${3 × 3 × 3 × 3 × 25 / 81 + {6 × 6× 6 × 5√5 / 27 - {2 × 2× 5/ 9 -{10× √5/ 3} -5 =0$

$25 + 40√5 - 20/9 - {10√5/ 3} -5 =0$

110√5/3 + 160/ 9 is not equal to 0

so√5/ 3 and - √5/ 3 are not roots of this equation
