Question

find a quadratic polynomial whose zeroes are - 11 and - 13​

Answer 1

Given :

• x = -11
• x = -13

To Find :

• Quadratic polynomial whose zeroes are -11 and -13.

Solution :

x = -11

$\longrightarrow$ (x + 11) = 0

x = -13

$\longrightarrow$ (x + 13) = 0

Multiplying (x + 11) and (x + 13)

$\longrightarrow$ (x + 11)(x + 13)

$\longrightarrow$ x² + 13x + 11x + 143

$\longrightarrow$ x² + 24x + 143

Another method to multiply -

$\longrightarrow$ (x + 11)(x + 13)

$\longrightarrow$ x(x + 13) + 11(x + 13)

$\longrightarrow$ x² + 13x + 11x + 143

$\longrightarrow$ x² + 24x + 143

Hence, The quadratic polynomial whose zeroes are - 11 and - 13 is x² + 24x + 143 .
