Question

Fine the factors By useing middle terms splitting method 1) 4×2-4×+1,2) ×2+7×+10​

Answer 1

Answer:

1)      x = 1/2     ;    x = 1/2

2)      x = -5       ;    x = -2

Step-by-step explanation:

1) 4x² - 4x + 1

  4x² - 2x - 2x + 1 = 0

  2x(2x - 1) - 1(2x - 1) = 0

  (2x - 1)(2x - 1) = 0

  2x - 1 = 0  ;   2x - 1 = 0

  2x = 1             2x = 1

   x = 1/2           x = 1/2

   

 

2) x² + 7x + 10

   x² + 5x + 2x + 10 = 0

   x(x + 5) + 2(x + 5) = 0

   (x + 5)(x + 2) = 0

   x + 5 = 0   ; x + 2 = 0

   x = -5           x = -2
