Question

x²-2x+15=0 facterization and Alfa and Beta​

Answer 1

Answer:

Can't be determined as roots are irrational.

Step-by-step explanation:

$2_-^+\sqrt{(2)^2-4(1)(15)} / 2\\\\= 2_-^+\sqrt{-56} / 2$

-ve sqrt can be computed thus roots cant be determined

Answer 2

Answer:

= x^2 - 2x-15

= x^2 -5x+3× -15

= x(×-5)+3(×-5)

=(×+3)(×-5)=0

= alfa= -3, beta = 5
