Question

p² - 10pq + __

Find the missing to complete perfect trinomial square

Answer 1

We know that ( p - x )² = p² - 2px + x²

Here , in p² - 10pq + _ , let us consider that "_" as ' x² '

Equating both equations...

p² - 2px + x² = p² - 10pq + x²

2px = 10pq

x = 5q

So, the the Equation is p² - 10pq + (5q)² = p² - 10pq + 25q²
