When the leading coefficient is 1,
If the constant ( c term) is a perfect square and the b term is 2* the square root of the c term.
Ex.
x*2 + 10x + 25
2*5 = 10 5*5=25
Ex.
x^2 - 12x + 36
2 * -6 = -12 6*6=36
You are finding the perimeter, which has double of each side length given.
Note: P = perimeter
2(5x - 1) + 2(2x + 1) = P
Distribute 2 to each monomial in the given parenthesis
2(5x - 1) = 10x - 2
2(2x + 1) = 4x + 2
10x - 2 + 4x + 2 = P
combine like terms.
P = 10x + 4x - 2 + 2
P = 14x
C) 14x, is your answer
