If 2y²-5 is divided by y-1.Solve by Remainder theorem​

Answer 1

Question :-

If 2y²-5 is divided by y-1.Solve by Remainder theorem.

Answer :-

• Reminder = -3

Step by step explanation :-

Remainder theorem :

a theorem in algebra: if f(x) is a polynomial in x then the remainder on dividing f(x) by x − a is f(a).

Now,

⇒ y - 1 = 0

⇒ y = 1

By remainder theorem,

Substitute y = 1 in 2y² - 5 then we get the remainder,

$\rm:\implies{2(1) {}^{2} - 5 } \\ \\\rm:\implies{2(1) - 5} \: \: \: \\ \\ \rm:\implies{2 -5 } \: \: \: \: \: \: \: \: \\ \\ \rm:\implies{ - 3} \: \: \: \: \: \: \: \: \: \: \: \:$
