3. now consider equations of the form x-a=sqrt (bx+c) where a, b, and c are all positive integers and b > 1
(a) create an equation of this form that has 7 as a solution and an extraneous solution. give the extraneous solution.
(b) what must be true about the value of bx+c to ensure that there is a real number solution to the equation? explain

X – a = sqrt( bx + c)

By using a = 5, b = 2/7 , c = 2

We can have an equation where the solution is 7

X – 5 = sqrt( 2/7 x + 2)

( x -5 ) ^2 = 2/7 x + 2

X2 – 10x + 25 = 2/7 x + 2

X2 – 72/7 x + 23 = 0

X = 7

X = 23/7

b. the value of bx+c must be positive so that there is a real number solution

the answers are in the images, i received 100% on this assignment. hope this !
