Question

Find
the zeros of the polynomial &
verify the relationship
their coeffoecient
x2+x-12=0​

Answer 1

${x}^{2} + x - 12 = 0$

Now follow the middle term split methods to find the zeroes.

${x}^{2} + (4 - 3)x - 12$

${x}^{2} + 4x - 3x - 12$

$x(x + 4) - 3(x + 4)$

$(x - 3)(x + 4)$

$x = 3$

$x = - 4$
