how do you solve
(17 - L)^2
Expand*
(17-l)^2
= (17-l)(17-l)
= 289 - 17l - 17l + l^2
= l^2 - 34l + 289
To solve the expression (17 - L)², you can follow these steps:
Step 1: Expand the expression
Using the formula for squaring a binomial, (a - b)² = a² - 2ab + b², the expression (17 - L)² can be expanded as follows:
(17 - L)² = (17)² - 2(17)(L) + (L)²
Step 2: Simplify the expanded expression
Simplifying the expanded expression, we have:
(17)² = 289
-2(17)(L) = -34L
(L)² = L²
Putting it all together, the simplified expression is:
(17 - L)² = 289 - 34L + L²
Therefore, the solution to the expression (17 - L)² is 289 - 34L + L².
