Question

factorise = 36p2- 84pq + 49q2

Answer 1

Answer:

(6p-7q)²

Step-by-step explanation:

As you see the equation 36p²=6p.6p

49q²=7q.7q

and 84pq=2.6p.7q

so using the formula (a-b)² = a² + b² - 2ab

we get 36p² - 84pq + 49p² = (6p-7q)²

Answer 2

Answer:

Step-by-step explanation:

this equation is a identity

the answer (6p+7q)^2
