Question

Ind all integers b such that x^(2)+bx+5 can be factored.

Answer 1

Answer:

All integers greater than 4 (5 or greater) and less than -4 (-5 or less)

Step-by-step explanation:

x² + bx + 5

b² - 4ac 》 0

b² - 4(1)(5) 》 0

b² - 20 》 0

b 》 sqrt(20)

b 》 4.47

b 《 -sqrt(20)

b 《 - 4.47

All integers greater than 4 (5 or greater) and less than -4 (-5 or less)

Answer 2

Answer:

so that the trinomial can be factored: x^2+bx+15. Algebra -> Polynomials-and-rational-expressions -> SOLUTION: Find all integers b so that the trinomial can be factored: x^2+bx+15 Log On. Algebra: Polynomials, rational expressions
