Question

A quadratic polynomial whose zeroes are subtract 3 and 4 is

Answer 1

$if \: \alpha \: and \: \beta \: are \: zeroes \: of \: polynomial \: \\ {x}^{2} - ( \alpha + \beta )x + \alpha \beta = 0 \\ = > {x}^{2} - 7x + 12 = 0$

hope it helps you

Answer 2

Answer: x^2 - x -12

Step-by-step explanation:

If a and b are zeroes of Quadratic Polynomial(QP) then QP be

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

= x^2- (-3+4) x + (-3) ×4

=x^2 - x -12
