Answer:

7x2 + 2√14x + 2 = 7x2 + 2√(7x2)x + 2 

=7x2 + 2√7√2x + 2

=(√7x)2 + 2√7√2x + (√2)2

= (√7x + √2)2 = (√7x + √2)(√7x + √2)........................Answer

40x7y2 - 135x4y5

= 5x4y2(8x3 - 27y3)

Using a3 - b3 = (a - b)(a2 + ab + b2)

= 5x4y2(2x - 3y)(4x2 + 6xy + 9y2)    ...............................Answer
