Question

Zeroes of the polynomial 2x^2-x-15=0. Show working as well.

Answer 1

Answer:

zeroes of the polynomial is 3 and -5/2

Answer 2

Step-by-step explanation:

f(x)=2x^2 - x - 15 =0

2x^2 -(6-5)x-15=0

2x^2 -6x +5x-15=0

2x(x-3)+5(x-3)=0

(2x+5)(x-3)=0

for zeros of polynomial

2x+5=0. x-3=0

2x=-5. x=3

x=-5/2
