Question

Answer it Please Answer I am not sure if you​

Answer 1

${x}^{2} - 2x - 15 \\ putting \: the \: value \: of \: x \\ {4}^{2} - 2(4) - 15 \\ 16 - 8 - 15 \\ - 7$

hope its help

Answer 2

Answer:

p(x) = x²-2x-15

when x=4 then,

p(4) = 4²- 2(4) - 15

p(4) = 16 - 8 - 15

p(4) = 8 - 15

p(4) = -7

so the value of the polynomial x²-2x-15 is -7 when x=4.

hope this answer is helpful to you.
