Question

Please help and explain :(

Answer 1

1st bring -square root of -5x to the right to make the square root of 11-x the subject.....then square both sides to get rid of the square root.....then solve...i hope i helped

Answer 2

nw square both sides and try to get rid of the 'root' signs.
on the right side you wil still hve a root sign whereas on the left side yu will have a linear equation.
square both sides again and then you will get a simple quadratic equation which can be solved by factorisation

Answer 3

thank you so much. but when I squared for the first time, why does the right side still have a root sign? @susan3

Answer 4

it cant u square both sides....if u square the left of equal sign then u must square the right....for example if u divide the left by 2 then u divide the right by 2....so if both sides are squared both square roots are gone

Answer 5

Because when you square the right side you get (a+b)^2=a^2 +2ab+b^2.
where b is your term with the root. to get rif of that u have to square both sides again.

Answer 6

rid*

Answer 7

;)

Answer 8

@susan3 ok thanks a lot! :) would x=-5/4 be the right answer?

Answer 9

x=-5/4 and x=-5
since u got a quadratic equation. u must get 2 roots.

Answer 10

Ok thanks!!! :)
