hope it helps you...

Answer 2

Solution :

Given zero = 2

Equation : x² + 3x + k

putting value of x = 2 in Given equation .

>> (2)² + 3 × 2 + k

>> 4 + 6 + k

>> 10 + k

>> k = -10

Hence

• value of k is - 10

TricK :

Whenever we get a zero of equation and equation is Given .

So,

The given zero is always equal to x.

By putting value of x we will get the value of k.
