Lol your a little kid but hold on
Angle DAB is equivalent to angle DCB. The answer is 65°
1) 5
2) zero
3) <span>Step 1: 12x + 15 = 12
Step 2: 12x = −3
4) 10
5) 2
This took me a long time to do so I hope this was beneficial :)) !! (btw I am absolutely sure about every answer. I checked my work plenty of times :)</span>
Answer:
f(x) =
is the required polynomial.
Step-by-step explanation:
Given the zeroes (roots) of the polynomial are
and
.
We know that complex roots occur in conjugate pairs.
So, this means that
and
would also be the roots of the polynomial.
If
are to be the roots of the polynomial then the polynomial should have been:
.
Now, to determine the polynomial for which
would be the roots.
Roots of the polynomial are nothing but the values of x (any variable) that would make the polynomial zero.
⇒ 
⇒ 
The required polynomial would be the product of all the above polynomials.

Multiply this to get the required equation.
⇒

∴ The required polynomial is x⁴ - 2x³ + 49x² - 18x + 360 = 0.
5(1.60+0.80)
(8+4)
12
