Question

find the zero of the polynomial 2x^+4x+2​

Answer 1

Answer:

Explanation:

2x² + 4x - 6 = 0

x² + 2x - 3 = 0

x² + 3x - x - 3 = 0

x(x + 3) - 1(x + 3) = 0

(x - 1) (x + 3) = 0

x = + 1, - 3

Sum of roots = -b/a

- 2 = -2

Product of roots = c/a

- 3 = - 3

Answer 2

Explanation:

2x^2+4x+2=0

2x^2+2x+2x+2=0

2x(x+1)+2(x+1)=0

(2x+2)(x+1)=0

2x+2=0 or x+1=0

x=-1 or x= -1
