Question

5n^2+23n−4186 split the middle term​

Answer 1

Answer:

Step-by-step explanation:

Example: Find the factors of 6x2 - 13x + 6

6x2 - 13 x + 6 ----->(1)

a.c = Product of 6 and 6 = 36

Factors of 36 = 2,18

= 3,12

= 4,9

Only the factors 4 and 9 gives 13-->(4 + 9)

For -13 , both the factors have negative sign. – 4 – 9 = - 13

Equation (1) ⇒ 6x 2 - 4x – 9x + 6

⇒2x ( 3x – 2 ) – 3 ( 3x – 2 )

⇒(3x – 2 ) ( 2x – 3) are the factors.

Answer 2

4n^+5n−636=0

4n^+53n−48n−636=0

n(4n+53)−12(4n+53)=0

(n−12)(4n+53)=0

n=12 or n=−4/53
