Question

find a quadratic polynomial with -7 as one of the zero and-15 as sum of the zeros

Answer 1

Hey Friend ☺

☆ QUADRATIC EQUATION ☆

Let the a & b be the zeros of the equation

a + b = - 15

a is given as - 7

- 7 + b = - 15

b = - 15 + 7

b = - 8

So the second zero is - 8

Then the quadratic equation is given as

x^2 + ( a + b ) x + ab

= x^2 + ( - 15 )x + - 7 × - 8

= x^2 - 15x + 56

So your required equation is x^2 - 15x + 56

Hope it helps you ..!!
