Question

A quadratic polynomiyal whose zeros are 1 and -3 is​

Answer 1

Answer:

x² +2x -3=0 is the answer ok :)

Step-by-step explanation:

Given that,

Zeroes of the quadratic polynomial are 1 and 1-3

Let,

α = 1

ß = (-3)

Sum of the zeroes => α + ß

                               => 1 + (-3)

                               => -2

 Product of the zeroes => α x ß

                                     =>  1 x (-3)

                                    => -3

quadratic equation general form :-

k(x² - (α + ß)x + αß )= 0 ------------------ (where k is constant)

=> k ( x² - (-2)x + (-3) ) =0

=> k ( x² +2x -3 ) =0

∴A quadratic polynomiyal whose zeros are 1 and -3 is​ x² +2x -3=0

Hence solved :)
