Question
If p = 35 - q - r and pq + r(p + q) = 324, then find the
value of (p² + q² + r²).Solution
We have, p = 35 - q - r
So, p + q + r = 35
And, pq + r(p + q) = 324
Or, pq + qr + pr = 324
Using, (p + q + r)² = p² + q² + r² + 2(pq + qr + pr)
35² = (p² + q² + r²) + 2 × 324
1225 = (p² + q² + r²) + 648
p² + q² + r² = 577
