Answer:

Step-by-step explanation:

-7x²+2x+1=0

By the quadratic formula we get,

x = -2±√2²-4(-7)÷2(-7)

x = -2±√4+28 ÷ -14

x = -2±4√2 ÷ -14

x = -1±2√2 ÷ -7

The possible values of x are -1+2√2÷ -7 and -1+2√2÷ -7

Step-by-step explanation:

x^2+2x+1=8x^2

(x+1)^2=(2×root(2)×x)^2

x+1=2×root(2) ×x

x(1-2×root(2))= -1

x= -1/(1-2×root(2))
