Find the Roots of the polynomial equation!!!

2x^3+2x^2-19x+20=0

Your given polynomial has only one real root which is x= -4

Step-by-step explanation:

find any zero of the polynomial.

x-a divides the polynomial where a is a zero of polynomial:

So x+4 divides

If we factor out a two, we can use the quadratic formula.

2(x^2-3x+2.5) so we have x = (-(-3)+/-(9-4*1*2.5)^(1/2))/2*1)=(3+i) or (3-i)/2 .

Final

then x=-4, (3+i)/2, or (3-i)/2

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

it is 570
