Question

if -1 is a zero if the polynomial p(x) x²-7x -8 then calculate the other zero
​

Answer 1

Answer:

Other zero is 8 and this polynomial will have only two zeroes because this equation is quardratic equation.

Step-by-step explanation:

${x}^{2} - 7x - 8$

${x}^{2} - 8x + x - 8$

$x(x - 8) + 1(x - 8)$

$(x + 1)(x - 8)$

$x = - 1 \: \:$

$x = 8$

The zeroes of the polynomial is -1 and 8
