Question

what number should be added to the polynomial x2+7x-35 so that 3 is the zero of the polynomial​

Answer 1

5 is the ans mmmmmmmmmmmmmm

Answer 2

Answer:

5

Step-by-step explanation:

polynomial P(x)

$polynomial P(x) = {x}^{2} + 7x - 35$

now,

$P(3) = {3}^{2} + 7 \times 3 - 35 \\ = 9 + 21 - 35 = - 5$

$P(3) = - 5 \\ P(3) + 5 = 0$

to make 3 as a zero of polynomial P(x) then we add 5 with polynomial P(x).
