Question

Write a quadratic function whose zeros are -5 and -6

Answer 1

A quadratic function whose zeros are -5 and -6 is $x^2+11x+30$

Step-by-step explanation:

We need to write a quadratic function whose zeros are -5 and -6

Zeros of quadratic equation means x=-5 ans x=-6

We can write it as: x+5=0 ans x+6=0

Multiply both zeros:

$(x+5)(x+6)\\=x(x+6)+5(x+6)\\=x^2+6x+5x+30\\=x^2+11x+30$

So, a quadratic function whose zeros are -5 and -6 is $x^2+11x+30$
