Question

Find the zeroes of
given quadratic polynomial
and verify relation between the zeroes
and its
coefficients.
2x²_18x +40​

Answer 1

Answer:

The orange divisor(s) above are the prime factors of the number 160. If we put all of it together we have the factors 2 x 2 x 2 x 2 x 2 x 5 = 160. It can also be written in exponential form as 25 x 51.

Answer 2

Answer:

2x²-18x+40

2x²-10x-8x+40

2x(x-5)-8(x-5)

(2x-8)(x-5)

2x-8 x=5

2x=8

x=4

Step-by-step explanation:

sum of zeros= 4+5=9

-b/a=-(-18)/2=9

product of zeros =4×5=20

c/a=40/2=20
