the question is a beat confusing please make it simplify
Answer:
Two complex roots.
Step-by-step explanation:
F(x)=2x^4 +5x^3 - x^2 +6x-1
is a polynomial in x of degree 4.
Hence F(x) has 4 roots. There can be 0 or 2 or 4 complex roots to this polynomial since complex roots occur in conjugate pairs.
Use remainder theorem to find the roots of the polynomial.
F(0) = -1 and F(1) = 2+5-1+6-1 = 11>0
There is a change of sign in F from 0 to 1
Thus there is a real root between 0 and 1.
Similarly by trial and error let us find other real root.
F(-3) = -1 and F(-4) = 94
SInce there is a change of sign, from -4 to -3 there exists a real root between -3 and -4.
Other two roots are complex roots since no other place F changes its sign
Answer:
20
Step-by-step explanation:
It's right triangle 45 45 90
The sides in this triangle<span> are in the ratio 1 : 1 : 1√2
if one side = </span>2√2 then b = 2√2
hypo. a = b(√2) = 2(2√2) = 4√2
answer
a = 4√2
b = 2√2
