Answer 1

hey!!!
do you know how to factor the quadratic equation ?

Answer 2

let sinx =x \[\huge\rm 7x^2-14x+2=-5\]
set it equal to 0

Answer 3

\(7\sin^2x-14\sin x+2=-5\)

Add 5 to both sides
\(7\sin^2x-14\sin x+7=0\)

Divide by 7
\(\sin^2x-2\sin x+1=0\)

Factor (that's a perfect square)
\((sin ~x - 1)^2=0\)

Answer 4

oh ok i get thank you peachpi
