The polynomial y = 2x3 + mx2

Mathematics
1 answer:
N76 [4]2 years ago
7 0

Answer:

2x³ + mx² - 13x + n

y = x - 2

x = 2

2(2)³ + m(2)² - 13(2) + n = 0

16 + 4m - 26 + n = 0

4m + n = 10. (1)

y = x - 3

x = 3

therefore 9m + n = -15

solving simultaneously

m = -5, n = 30

m + n = 25

Solve for c.<br><br> a(c−b)=d
tatiyna

Answer:

c= ab + d/ a

Step-by-step explanation:

Let's solve for c.

a(c-b)=d

Step 1: Add ab to both sides.

-ab + ac + ab = d+ ab

ac = ab + d

Step 2: Divide both sides by a.

ac / a = ab + d / a

c = ab + d/ a

Answer:

c= ab + d/ a

Hope this helps ☝️☝☝
