(3).t sq+9-6t

Answer 2

Hello users..

Using formula
(a+b)² = a²+ b²+2ab
&
(a-b)² = a² + b²-2ab

Here
(1.)Using formula
(a+b)² = a²+ b²+2ab

(p+5)² = p² +5² + 2×p×5
=( P² +25 +10p)

(2.)Using formula
(a+b)² = a²+ b²+2ab

(3x +1/3x)² = (3x)² + (1/3x)² +2×(3x)×(1/3x)
= 9x² + 1/9x² + 2
= (9x² + 1/9x² +2)

(3.) using formula
(a-b)² = a² + b²-2ab

(t-3)²= t² + 3² -2×t×3
= t² +9 -6t
= (t² +9 -6t)
