If a and ß are zeroes of x^2+ 5x + 5, find the value of a^-1 + ß^-1

Answer 1

✨✨✨✨ANSWER ✨✨✨

✓✓✓P[X]=x^2+ 5x + 5 ✓✓✓

• now the roots are a and b

• now ....(a+b)=-5
• and ......ab=5

• now...

$= a {}^{ - 1} + b {}^{ - 1} \\ = \frac{1}{a} + \frac{1}{b} \\ = \frac{a + b}{ab} \\ = \frac{ - 5}{5} \\ = - 1$

✓✓✓the value is = -1✓✓✓✓
