Find all Values of b that will make the polynomial a perfect square trinomial.

weeeeeb [17]

Answer:

10,404/334,084

Step-by-step explanation:

Given the polynomial

289r^2 - 102r + c

We are to find the value of c that will make it a perfect square

Divide through by 289

289r²/289 - 102r/289 + c/289

Half of the coefficient of r is 1/2(102/289)

Half of the coefficient of r = 102/578

Square the result

r² = (102/578)²

r² = 10,404/334,084

Hence the required constant is 10,404/334,084

perimeter of a rectangle = 2( width + length )

P = 2 ( x - 2 + x + 7 )

P = 2 ( x + x + 7 - 2 )

P = 2 ( 2x + 5 )

P = 4x + 10
