Question

Find the square of 5x +6​

Answer 1

Answer:

25x² + 60x + 36

Step-by-step explanation:

GIVEN :

5x + 6

TO FIND :

Square of 5x + 6 or (5x + 6)²

SOLUTION :

We know that,

(a + b)² = a² + 2ab + b²

(5x + 6)² = (5x)² + 2×(5x)×(6) + (6)²

= 25x² + 60x + 36

Therefore the square of (5x +6 ) = 25x² + 60x + 36
