Given:
To find:
coefficeint of x³,x²,x
Explanation:
Now
↔Coefficeint of x³=2
↔Coefficient of x²=(-7)
↔Coefficient of x=-7
More information:
For a cubic polynomial,
↔α+β+δ=-b/a (sum of roots)
↔αβ+βδ+βα=c/a
↔αβδ=-d/a(product of roots)
What is a Coefficeint?
↔Coefficient is a constant that is before a variable for a polynomial
for example
f(x)=x²-3
Here, Coefficeint of x²=1
