Question

factorise 9x^2+24XY + 16y^2 ​

Answer 1

Answer:

Explanation:

Note that:

9x2=(3x)2

24xy=2(3x)(4y)

16y2=(4y)2

So:

9x2+24xy+16y2=(3x)2+2(3x)(4y)+(4y)2

is in the form:

A2+2AB+B2=(A+B)2

So putting A=3x and B=4y we have:

9x2+24xy+16y2=(3x+4y)2

Answer 2

Answer:

49 + x³ + y³.

Step-by-step explanation:

9x² + 24xy + 16y² 9+24+16+x²+x+y+y² 49 + x³ + y³. Mark as brainliest
