..........
. factorise please fast​

Answer 1

Answer:

(3+a+x)(3-a-x)

Step-by-step explanation:

9 - (a+x)²

= 3² - (a+x)²

= (3+a+x)(3-a-x) [a² - b² = (a+b)(a-b)]

Answer 2

$\huge{\mathcal{\pink{A}\green{N}\red{S}\blue{W} {E}\green{R}}}$

9-(a+x)²

9 = 3*3=3²

3²-(a+x)²

a²-b²=(a+b)(a-b)

3²-(a+x)² = (3 +{a+x}) + (3-{a+x})

multiplying sign outside the {a+x}

              = (3+a+x)(3-a-x)
