Question

factorise the quadratic polynomial by splitting the middil term method 5x²+x-6​

Answer 1

$= 5 {x}^{2} + x - 6$

$= 5 {x}^{2} + ( 6 - 5)x - 6$

$= 5 {x}^{2} + 6x - 5x - 6$

$= x(5x + 6) - 1(5x + 6)$

$= (x - 1)(5x + 6)$

Answer 2

Answer:

= 5x^2 + x - 6 = 5x^2 + x − 6.

= 5 {x}^{2} + ( 6 - 5)x - 6

= 5x^2 + (6−5)x−6

= 5x^2 + 6x - 5x - 6

= 5x^2 + 6x−5x−6

= x(5x + 6) – 1(5x + 6) = x(5x+6) − 1(5x+6)

= (x - 1)(5x + 6) = (x−1)(5x+6).
