HI I JUST DID THE FIRST ONE . SORRY I CAN'T ANSWER THE 5TH AND6th IT'S HARD
Answer:
(x - 6)(x - 6)
Step-by-step explanation:
The given quadratic equation is
.
A quadratic equation can be factored in the form
where
and
will form the roots of the equation.
Here the roots are:
.
The factored form would simply be:
.
2sin²(-2490)+tan 1410=2sin²(-330-6*360)+tan (330+3*360)=
=2sin²(-330)+tan (330)=2 sin²(30-1*360)+tan (-30)=
=2sin²(30)-tan (30)=2(1/2)²-√3/3=1/2-√3/3)=(3-2√3)/6
Answer: 2 sin²(-2490)+tan (1410)=(3-2√3)/6 (≈-0.07735...)
Answer:
5/8
