Polynomials
1. Find the zeros of the quadratic polynomial and Verify the relationship between its
zeros and
coefficients
a.
x2 + 3x – 10 b. 6 x2
-7x – 3
c.
4x2 - 4x – 3
d. 2x2 - 11x +
15
e. x2 – 10 f. . x2 – 5
g.
5 x2 – 25 h. 3 x2 + 5x – 8
i.
2 y2 - 2√2 y + 6
j. y2 -
3y + √3
2
.Divide p(x) by q(x)
a.
p(x) = 2 x2 +
x – 15 , q(x) = x + 3
b. p(x) = 12 -17 x – 5x2 , q(x)
= 3 – 5x
c. p(x) = 3x3 - 4x2 +7x – 2 ,
q(x) = x2 – x +2
d.
p(x) = 6 + 19 x +x2 - 6x3,
q(x) = 2
+ 5 x –
3x2
e.
p(x) = 3 - x + 2x2
, q(x) = 2 – x
