find the zeros of the polynomial 2 x square - 3 x minus 2
Answers
p(x)= 2x²-3x-2
To Find : The zeroes of the above polynomial.
Solution :
2x²-3x-2 = 0
2x²-4x+x-2 = 0
2x(x-2)+1(x-2) = 0
(x-2)(2x+1) = 0
Here, x = 2 and x = -½.
What is a polynomial?
A polynomial is an algebraic expression having the degree of it's variables as a whole number.
For example - 2, x , x+4, 4x³ etc.
The classification of polynomials can be done in two ways :
• On the basis of degree :
★ Linear Polynomial - The polynomial having the degree = 1
★ Quadratic Polynomial - The polynomial having the degree = 2
★ Cubic Polynomial - The polynomial having the degree = 3
• On the basis of terms :
★Monomial : The polynomial having a single term only.
★ Binomial : The polynomial having two terms.
★ Trinomial : The polynomial having 3 terms.
