If the zeroes of the quadratic polynomial x ^ 2 + (a + 1) * x + bare 2...
Explanation:
Given:
The quadratic polynomial is x^2 + (a + 1)x + b.
Given zeroes:
Let the zeroes be -3 and 2.
Using sum and product of zeroes:
Sum of zeroes = -3 + 2 = -1
Product of zeroes = -3 * 2 = -6
Comparing with the general form:
Sum of zeroes = -b/a = -1
Product of zeroes = c/a = -6
Solving for a and b:
From the sum of zeroes, we get:
-b/a = -1
b = a
From the product of zeroes, we get:
c/a = -6
b = -6a
Substitute b = a in b = -6a:
a = -6a
7a = 0
a = 0
Substitute a = 0 in b = a:
b = 0
Therefore, a = 0 and b = -6.
So, the correct option is:
d. a = 0, b = -6
Given:
The quadratic polynomial is x^2 + (a + 1)x + b.
Given zeroes:
Let the zeroes be -3 and 2.
Using sum and product of zeroes:
Sum of zeroes = -3 + 2 = -1
Product of zeroes = -3 * 2 = -6
Comparing with the general form:
Sum of zeroes = -b/a = -1
Product of zeroes = c/a = -6
Solving for a and b:
From the sum of zeroes, we get:
-b/a = -1
b = a
From the product of zeroes, we get:
c/a = -6
b = -6a
Substitute b = a in b = -6a:
a = -6a
7a = 0
a = 0
Substitute a = 0 in b = a:
b = 0
Therefore, a = 0 and b = -6.
So, the correct option is:
d. a = 0, b = -6
