Question

a²+(b²/4)+(c²/9)+ab+(bc/3)+(2ca/3) factorise

Answer 1

a²+(b²/4)+(c²/9)+ab+(bc/3)+(2ac/3)
(a) ²+(b/2)²+(c/3)²+2(a) (b/2)+2(b/2)(c/3)+2(a) (c/3)

(a+b/2+c/3)²
(a+b/2+c/3)(a+b/2+c/3)

Answer 2

Answer:

Pls mark as brainliest

Step-by-step explanation:

a²+(b²/4)+(c²/9)+ab+(bc/3)+(2ac/3)

(a) ²+(b/2)²+(c/3)²+2(a) (b/2)+2(b/2)(c/3)+2(a) (c/3)

(a+b/2+c/3)²

(a+b/2+c/3)(a+b/2+c/3)
