Question

please give the answer it is very urgent .if you don't know means leave it. but don't give wrong answer please .subject maths. class 9th. give step by step explanation.​

Answer 1

Step-by-step explanation:

Since x-2 is the factor of x²+5x+a,

then 2 is the zero of polynomial x²+5x+a

When we put value of 2 in x²+5x+a=0

4+10+a=0

14+a=0

a= -14

Answer 2

Answer:

a = -6

Step-by-step explanation:

p(x)=x³-3x²+5x+a

x=2

therefore, (2)³ - 3(2)² + 5(2) + a

= 8-3(4)+10+9

=8-12+10+a

=8+10-12+a

=18-12+a

=6+a

-6=a

Therefore, a= -6
