Question

. If x³ + ³ × 15 = ² + ² then is​

Answer 1

we know that if x−α is a factor of p(x) then p(α)=0

then

p(3)=0

(3)

2

−a(3)−15=0

9−3a−15=0

3a=−6

a=−2

Answer 2

Step-by-step explanation:

Correct option is A)

Given x−3 is a factor x

2

−ax−15

Let p(x)=x

2

−ax−15

we know that if x−α is a factor of p(x) then p(α)=0

then

p(3)=0

(3)

2

−a(3)−15=0

9−3a−15=0

3a=−6

a=−2
