8h + (-6.9d) -18 + 5d -3.4h help
pishuonlain [190]

Answer:

−1.9d + 4.6h − 18

Explanation:

8h − 6.9d − 18 + 5d − 3.4h

= 8h + −6.9d + −18 + 5d + −3.4h

[ Combine Like Terms ]

= 8h + −6.9d + −18 + 5d + −3.4h

= (−6.9d + 5d) + (8h + −3.4h) + (−18)

= −1.9d + 4.6h + −18

Use the the factor theorem to determine wether the first polynomial is a factor of the second. X-3; 2x^2-4x+30
Firdavs [7]
Given the polynomial function 

P(x)=2 x^{2} -4x+30

If (x-3) is a factor of P(x), then

P(x)=2 x^{2} -4x+30=(x-3)*Q(x), for some polynomial Q of 1st degree,

Then according to the factor theorem P(3)=0, because P(3)=(3-3)Q(x)=0*Q(3)=0.

Check

P(3)=2 (3)^{2} -4(3)+30=18-12+30=36≠0


we see that P(3) is not 0, so (x-3) is not a factor of P(x).
