Question

Factorize: : 81 + 18x + x2​

Answer 1

Answer:

7 − 2 ( 5 − 3 ) = 4 ( − 3 ) + 3

7 − 2 ( −3 + 5 ) = 4( − 3 ) + 3

7 −2( − 3 + 5 )=4 ( − 3 ) + 3

7 + 6 − 1 0 = 4 (−3 ) + 3

7 +6 − 1 0 = 4 ( − 3 ) + 3

− 3 + 6 =4 ( − 3) +3

− 3 + 6 = 4 ( -3 ) + 3

6  − 3 = 4 ( − 3 ) + 3

6 − 3 = 4 ( − 3 )+ 3

6 − 3 = 4 − 1 2 + 3

simplify

= = − 3

Answer 2

Step-by-step explanation:

$x ^{2} + 18x + 81$

$x ^{2} + 9x + 9x + 81$

$x(x + 9) + 9(x + 9)$

$(x + 9)(x + 9)$

$x = - 9 \: and \: - 9$
