Question

3. Factorise the following using appropriate identities.
(1) 16x2 + 24xy +9y?
(ii) 4y2 – 4y +1
(iii)4x^2-y^2÷25​

Answer 1

Answer:

Step-by-step explanation:

We know 16x  

2

+24xy+9y  

2

 =(4x)  

2

+2(4x)(3y)+(3y)  

2

 

We know appropriate identities is x  

2

+2xy+y  

2

=(x+y)  

2

 

Here x=4x and y=3y

Thus (4x)  

2

+2(4x)(3y)+(3y)  

2

 =(4x+3y)
