14. 36x^2 - 16
      4(9x^2 - 4) =
      4(3x + 2)(3x - 2) <==

15. 3x^2 + 10x - 8
      (3x - 2)(x + 4) <==

16. 5x^2 - 16x + 15 = 4x - 5
      5x^2 - 16x - 4x + 15 + 5 = 0
      5x^2 - 20x + 20 = 0
      5(x^2 - 4x + 4)
      5(x - 2)(x - 2)
      x - 2 = 0....x = 2

Solve this expression 8÷2*5+(6-4)
Annette [7]

Value of expression \frac{8}{2}(5) + (6-4) is 22 .

<u>Step-by-step explanation:</u>

Here we have the following expression to solve :

8÷2*5+(6-4)

⇒ (8/2)*5 + (6-4)

⇒ \frac{8}{2}(5) + (6-4)

But 8 = 4(2) , So

⇒ \frac{4(2)}{2}(5) + (6-4)

⇒ 4(5) + (6-4)

⇒ 20 + (6-4)

⇒ 20 + 2

⇒ 22

Therefore, Value of expression \frac{8}{2}(5) + (6-4) is 22 .
