(5x+1)² = 7; expand: 25x² + 10x +1 = 7 or 25x² + 10x -6 = 0
Solve this quadratic for x:
x = [-b + √(b² - 4ac)]/2a and x = [-b - √(b² - 4ac)]/2a
Plug the values and you'll find :
x = (- √7 - 1)/5 (answer C)
x = (+√7 -1)/5 (answer E)
Median = 11. Sorry if wrong
If right, pls mark brainliest i wanna get virtuoso.
Have a great day
It is okay to take the inverse of both side given that you remember to exclude the value that make the denominator zero which is in this case r=-1
