Question

if the volume of a cuboid is 2 x square - 16 then find its possible dimensions​

Answer 1

2x²-16

(√2x)²-(4)²

(√2x+4)(√2x-4)=0

Possible dimension are

x = 4/√2 = 2√2

x= -4/√2 = - 2√2

Answer 2

Question :-

if the volume of a cuboid is 2 x square - 16 then find its possible dimensions

Solution :-

Applying this identity a²-b² = (a+b)(a-b)

2x² - 16

(√2)²- (4)²

(√2x+4)(√2x-4)

Possible dimension are

x = 2/√2

or

x = -2√2
