Question

factorise the following ​

Answer 1

Answer:

(a). 64x²+16x+1

64x²+8x+8x+1

8x(8x+1) +1(8x+1)

(8x+1) (8x+1)

Answer 2

Answer:

a) 64x2 + 16x +1

= 64x² + 16x +1

= 64x² + 8x+8x +1

= 8x (8x +1) + 1(8x+1)

= (8x+1)(8x+1)

= (8x+1)²

To solve the value of x ,

we can equate it with zero

i.e

or 8x+1= 0

x= -1/8
