Which expression is a difference of squares with a factor of 2x5?
Sedbober [7]

Answer:

{( \sqrt{3.5} })^{2}  -  {( \sqrt{1.5} )}^{2}

Step-by-step explanation:

The difference of two squares identity is

{x}^{2}   -  {y}^{2}  = (x  - y)(x + y)

When we let

\sqrt{3.5}

and

\sqrt{1.5}

, we get:

{( \sqrt{3.5} )}^{2}  -  {( \sqrt{1.5}) }^{2}  = (3.5 - 1.5)(3.5 + 1.5)

This will simplify to give us the required factors

{( \sqrt{3.5} )}^{2}  -  {( \sqrt{1.5}) }^{2}  =2 \times 5
