What is the expression in factored form?x^2+13x+14Also an explanation
I dont understand this math at all

Answers

Answer 1
Answer:

Answer:

\left(x-(-13+√(113))/(2)\right)\left(x-(-13-√(113))/(2)\right).

Step-by-step explanation:

To factor the expression x^2+13x+14 you need to know its roots.

First find the discriminant of this quadratic polynomial:

D=13^2-4\cdot 1\cdot 14=169-56=113.

Then the roots of the expression x^2+13x+14 are

x_(1,2)=(-13\pm √(113))/(2).

Now the factored form is

\left(x-(-13+√(113))/(2)\right)\left(x-(-13-√(113))/(2)\right).

Which pair of values satisfy this inequality?
a. h = 2 and a = 1
b. h = 6 and a = 2
c. h = 10 and a = 3
d. h = 20 and a = 6

Answers

h < 4a – 3
(2) < 4(1) - 3
2 < 4 - 3
2 < 1
Not True

h < 4a – 3
(6) < 4(2) - 3
6 < 8 - 3 
6 < 5
Not True

h < 4a – 3
(10) < 4(3) - 3
10 < 12 - 3
10 < 9
Not True

h < 4a – 3
(20) < 4(6) - 3
20 < 24 - 3
20 < 21
True

Answer: (d) h = 20 and a = 6
