Question

find the value of the polynomial y2 -5y+6 at y=1

Answer 1

Hello!

• p(y) = y² - 5y + 6

• p( 1 ) = ( 1 )² - 5( 1 ) + 6

⇒ 1 - 5 + 6

⇒ 1 + 1 ⇒ 2

Therefore,

$\boxed{\sf p( 1 ) : y^{2} - 5y + 6 = 2}$

Cheers!

Answer 2

Step-by-step explanation:

if y =1 , then

$y {}^{2} - 5y + 6 =(1) {}^{2} - 5 \times 1 + 6 \\ = 1 - 5 + 6 \\ = 2$
