man how df you do dis

Answer 1

Answer:

-2.9375

Step-by-step explanation:

2x-14x+47=0

16x+47=0

16x=-47

x=-2.9375

Answer 2

Answer:

x=7+√ 2 or x=7-√ 2

Step-by-step explanation:

x^2-14x+47=0

Completing the square,

x^2-14x+49-2=0

x^2-14x+49=2

x^2-7x-7x+49=2

x(x-7)-7(x-7)=2

(x-7)^2=2

x-7=√ 2 or x-7=-√ 2

x=7+√ 2 or x=7-√ 2
