Answer 2

The quadratic polynomial whose zeroes are 3 and -4​ is:

$x^2+x-12$

Solution:

Given that,

Zeros of quadratic polynomial are 3 and -4

Convert the zeros to factors.  Multiply the factors to get quadractic polynomial

x = 3 and x = -4

x - 3 = 0 and x + 4 = 0

Thus the factors are x - 3 and x + 4

Thus the quadractic polynomial is:

Multiply the above two factors

$(x-3)(x+4)\\\\Expand\\\\x^2 +4x -3x -12\\\\x^2 +x - 12$

Thus the quadratic polynomial is found
