How do you solve #(x-1)^2=49#?

Answer 1

I found:
#x_1=8#
#x_2=-6#

Take the square root of both sides and get: #x-1=+-sqrt(49)=+-7# rearranging to isolate #x# you get two solutions: #x_1=1+7=8# #x_2=1-7=-6#

To solve the equation ((x - 1)^2 = 49), you can take the square root of both sides of the equation. This gives you (x - 1 = \pm 7). Then, solve for (x) by adding 1 to both sides of the equation. So, (x = 1 \pm 7), which gives you two solutions: (x = 8) and (x = -6).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
