Answer:
[tex] {( \sqrt{3.5} })^{2} - {( \sqrt{1.5} )}^{2} [/tex]
Step-by-step explanation:
The difference of two squares identity is
[tex] {x}^{2} - {y}^{2} = (x - y)(x + y)[/tex]
When we let
[tex] \sqrt{3.5} [/tex]
and
[tex] \sqrt{1.5} [/tex]
, we get:
[tex] {( \sqrt{3.5} )}^{2} - {( \sqrt{1.5}) }^{2} = (3.5 - 1.5)(3.5 + 1.5)[/tex]
This will simplify to give us the required factors
[tex] {( \sqrt{3.5} )}^{2} - {( \sqrt{1.5}) }^{2} =2 \times 5[/tex]
