<em><u>Answer</u></em>:

The quadratic equation is : x²+x+1=0

<u><em>Step-by-step explanation:</em></u>

Generally:

let S be the sum of the roots z₁ and z₂

and P be the product of the roots z₁ and z₂

then z₁ and z₂ are the solutions for the equation: x² − Sx + P = 0

Now,

S=-1 and P=1 then the equation is x²+x+1=0.

Simplify (sin^2 0+cos^2 0) (sin 0+cos 0)<br> Can someone help? I don’t understand.

Answer:

C) $sin\theta+cos\theta$

Step-by-step explanation:

$(sin^2\theta+cos^2\theta)(sin\theta+cos\theta)$

$sin\theta+cos\theta$

Recall the Pythagorean Trigonometric Identity where $sin^2\theta+cos^2\theta=1$ , so $1(sin\theta+cos\theta)=sin\theta+cos\theta$
