Question

) Factorise : 4x2 + 9y2 + 16z2 + 12xy -24xy – 16xz​

Answer 1

We know that,

a

2

+b

2

+c

2

+2ab+2bc+2ac=(a+b+c)

2

Now,

4x

2

+9y

2

+16z

2

+12xy−24yz−16xz

=(−2x)

2

+(−3y)

2

+(4z)

2

+2(−2x)(−3y)+2(−3y)(4z)+2(−2x)(4z)

=(−2x−3y+4z)

2

=(−2x−3y+4z)(−2x−3y+4z)

hope itz help u
