Question

Factorise the following polynomials.
x^2/4y^2+2/3+4y^2/9x^2​

Answer 1

Step-by-step explanation:

9x

2

+4y

2

+16z

2

+12xy−16yz−24xz

=(3x)

2

+(2y)

2

+(−4z)

2

+2(3x)(2y)+2(2y)(−4z)+2(−4z)(3x)

=(3x+2y−4z)

2

=(3x+2y−4z)(3x+2y−4z)

Hence facorise.

Formula:

(a+b+c)

2

=a

2

+b
