Answer:
Step-by-step explanation:
whitch answer how do you want us to answer
as the product of 90 degrees and 20 degrees
30x60=1800
90x20=1800
-2=-x+x square-4
firstly regroup the equation
x square-2x+x-2=0
x square-x-2=0
multiply the first term by the last term.(I.e x square multiply by -2=-2x square)
product of factor = -2x 1
sum of factor= -2x+1(x)= -1
x square -2x+x-2=0
open the bracket:
x(x-2)+1(x-2)=0
x=1 or x=-2
Therefore; x=-1 or x=2
Answer:
coefficient of the term of degree 4 in this polynomial is 3
