Question

solve the following quadratic equations by factoriesation method. 1). x^2+6x+8=0​

Answer 1

,The zeroes are 2 and 4

Explanation:

x

2

- 6x + 8 = 0

x

2

- 4x -2x + 8 = 0

x(x - 4) - 2(x - 4) = 0

(x - 2)(x - 4) = 0

x - 2 = 0 or x - 4 = 0

x = 2 or x = 4

4

Answer 2

Answer:

Step-by-step explanation:

=> x^2 + 6x + 8  

=> x^2 +4x + 2x + 8

=> x(x + 4) + 2(x + 4)

=> (x + 2)(x + 4)

Therefore , x = -2 or x = -4
