What are the solutions to the equation root x^2+2x-10 = root x+20 x = –6, x = –5
x = –6, x = 5
x = –5, x = 6
x = 5, x = 6

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

Ireally don’t understand your problem do you have a better picture of it
