Answer with explanation:
We have to Write 85 ,53 and 169 as sum of three prime numbers.Prime numbers are those numbers which has only two factors , 1 and itself.
→ 85=13+29+43
→ 53=5+7+41
→169=7+61+101
Answer:
x^2 + {a/(a + b) + (a + b)/a}x + 1 = 0
Delta = {a/(a + b) + (a + b)/a}^2 - 4
= {a/(a + b)}^2 + {(a + b)/a}^2 + 2 - 4
= {a/(a + b)}^2 + {(a + b)/a}^2 - 2
= {a/(a + b) - (a + b)/a}^2
If a is not equal to zero and a is not equal to -b => delta is always larger than 0
=> Solution 1 = - [ {a/(a + b) + (a + b)/a} + |{a/(a + b) - (a + b)/a}| ]/2
=> Solution 2 = - [ {a/(a + b) + (a + b)/a} - |{a/(a + b) - (a + b)/a}| ]/2
Hope this helps!

Step-by-step explanation:
Please see the pic, I'd solved in it.
If you take away the 0s you can multiply 8 and 3. sooooo
