Remainder theorem question(screenshot included)

c = 5

using the Remainder Theorem.

If a polynomial f(x) is divided by (x - a) then remainder is f(a)

for (x - 2 ) → a = 2

evaluating the polynomial f(2) gives

f(2) = 2(2)³ -c(2)² +4(2) - 7 = - 3 = 16 -4c + 8 - 7 = -3 → ( solve for c )

17 - 4c = - 3 → - 4c = - 3 - 17 = - 20 ⇒ c = 5

f(x) = 2x³ -5x² + 4x - 7

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
