Step-by-step explanation:
Answer:
2 & +2i
Step-by-step explanation:
The two additional roots of the polynomial functions are:
1. 7-5 = 2
2. Irrational root of a polynomial functions are always in pairs, hence
- 2i will have +2i as its pair
Answer:
i did the first
Step-by-step explanation:
1st way
Standard form: a(X-h)²+k = ( -2/3X² -16/3X -32/3) +32/3 -17/3 = -2/3(X +4)² +5
y = -2/3*X^2-16/3*X-17/3
X = -4 ±√( 15/2) = -6.7386, or -1.2614
Axis of symmetry: X= -4; Vertex (maximum)=(h,k)=( -4, 5); y-intercept is (0,-5.66666666667)
two real roots: X=-1.2613872124776866 and -6.738612787477313
