Question

draw the graph of each of the following polynomials and determine the zeroes of the following (i)2x2-9x+10
(ii)x3-x2​

Answer 1

Step-by-step explanation:

1. a=2, b= -9, c=10

-b±root(b^2 - 4ac) / 2a

9 ± root of (81-4*2*10)/4

9 ±root of (81-80)/4=9 ± root of (1)/4

= 9±1 /4

10/4 & 8/4

5/2 & 2 are zeros

2. x3-x2 =

x^3 =x^2

x=1

1, 0, 0 are roots
