Explain why the equation (x-3)^2-38=11 has two solutions. Then solve the equation to find the solutions. Show your work.
skelet666 [1.2K]

Answer:

X = 10 and X = -4

Step-by-step explanation:

(x-3)^2-38=11

(x-3)^2 = 11 +38

(x-3) ^2 = 49

Taking square root on both sides

√(x-3) ^2 = √ 49

X-3 = +7, -7

X = 7 +3,    X= -7+3

X = 10        X = -4

So, it has got two solutions

Place the comma in the position in the answer<br><img src="https://tex.z-dn.net/?f=4.7%20%5Ctimes%202.9%20%3D%201316" id="TexFor
MaRussiya [10]

First of all, 4.7 * 2.9 = 13.63, so I think a mistake has occurred there and second, comma does not come here because this is not a big number, it is a small number. If you meant a dot instead. it would placed in the middle AKA 13.63
