Question

Factorise a square + 6a + 9​

Answer 1

Answer:

( a + 3 ) ( a + 3 )

Step-by-step explanation:

a^2 + 6a + 9

= a^2 + 3a + 3a + 9

= a ( a + 3 ) + 3 ( a + 3 )

= ( a + 3 ) ( a + 3 )

Answer 2

• a²+6a+9
• a²+6a+3²
• a²+2×a×3+3²
• (a+3)²

by {(a²+2ab+b²) = (a+b)²}

so the answer is

(a+3)² =

= (a+3)(a+3)

hope it helps.
