Explanation:
'u squared minus t squared' is u²-t².
If we use the difference of two squares theorem we can write it as:
[tex]u^2-t^2=(u+t)(u-t)[/tex]We have that
• u + t = 8
,• u - t = 3
So u squared minus t squared is:
[tex]u^2-t^2=(u+t)(u-t)=(8)(3)=24[/tex]Answer:
The value of u squared minus t squared is 24
