## ashking1 one year ago can some one help me with this question https://gyazo.com/6ed19fc4e1c6e209bfe2521d400bb387

1. Nnesha

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

2. Nnesha

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

3. anonymous

$$7\sin^2x-14\sin x+2=-5$$ 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) $$(sin ~x - 1)^2=0$$
