Solve quadratic equation 4(x-3)^2=25

x = 11/2                 x = 1/2

Step-by-step explanation:

4(x-3)^2=25

Divide each side by 4

4/4(x-3)^2=25/4

(x-3)^2=25/4

Take the square root of each side

sqrt((x-3)^2)=± sqrt(25/4)

(x-3)=± sqrt(25)/ sqrt(4)

x-3 = ± 5/2

Separate into two equations

x-3 = 5/2             x-3 = -5/2

Add 3 to each

x-3+3 = 5/2+3     x-3+3 = -5/2+3

x = 5/2+6/2           x = -5/2 +6/2

x = 11/2                 x = 1/2

{1/2, 11/2}

Step-by-step explanation:

Take the square root of both sides, obtaining

2(x - 3) = ± 5

This produces two valid answers/solutions:

x - 3 = 5/2, or x = 11/2, and

x - 3 = -5/2, or x = 1/2

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
