Question

FIND THE ZERO OF POLYNOMIAL 2x³+5x²-5x-2

Answer 1

p(1)=0
so, (x-1) is a zero
after this, u can divide (x-1) by the given polynomial by long division method.
 the quotient u get can be divided into two by using splitting the middle term method. and u get 3 factors. done!

Answer 2

For x=1, p(1)=2(1)^3+5(1)^2-5(1)-2=2+5-5-2=0 hence, zero of the polynomial is 1.
