Question

If one zero of the quadratic polynomial x² + 3x + b is 2, then the value of b is​

Answer 1

Answer:

-10

Step-by-step explanation:

Since one of the zero is 2 substituting it,

(2)²+3(2)+b = 0

4+6+b = 0

10+b = 0

b = -10

Answer 2

Answer:

If one zero of the quadratic polynomial x² + 3x + b is 2, then the value of b is​ -10.

Step-by-step explanation:

Given quadratic polynomial is x² + 3x + b

and given that 2 is the zero of the quadratic polynomial x² + 3x + b

then, 2 is a zero of x^2 + 3x + b

Hence, (2)^2 + 3(2) + b = 0

b + 10 = 0

b = −10
