Answer 1

Answer:

y² + 2y - 3 when y =2

=$2^2+2*2-3$

=$4+4-3$

=5

Answer 2

Answer:

y² + 2y -3 is a quadratic trinomial

Step-by-step explanation:

y=2

2² + 4 -3

(4+4)-3 = 8-3 = 5

if the value of the variable is not given, you need to solve the expression like this:

y² + 3y - 1y - 3

y (y+3) - 1 (y+3)

= (y-1) (y+3)
