Question

Given (x – 7)2 = 36, select the values of x. х = 13 х = 1 x = -29 х = 42 ОО

Answer 1

Answer:

$x_{1} = 1\\\\x_{2} = 13$

Step-by-step explanation:

(x – 7)^2 = 36

x^2 -14x +49 =36

x^2 -14x +13= 0

using quadratic formula

$x =\frac{-b+-\sqrt{b^{2}-4*a*c}}{2*a}$

a= 1  b= -14    c =13

we have:

$x_{1} = 1\\\\x_{2} = 13$

Answer 2

13 my dude hope it’s right
