Answer 1

Hope it will help...

Answer 2

Answer:

2x*2 - x - 15

Step-by-step explanation:

to find a quadratic polynomial if the zeroes are given, we can use the following equation-

k( x*2 + ( alpha + beeta) x + alpha * beeta

where k can be any number ( 1 is more likely )

alpha is one zero and beeta is the other

alpha is given 2/5 and beeta is -3

substituting--

k( x*2 +(5/2+-3)x+ 5/2 * -3

now multiple the whole equation by 2

2x*2 - x - 15

hence its the required quadratic equation
