Question

Zeros of polynomial 2x squire Plus 2x - 12 hour

Answer 1

Answer:

2x²+2x-12

Solⁿ= 2x²+6x-4x-12

2x(x+3)-4(x+3)

(x+3) (2x-4)

Zeroes of :-

x+3 = 0. 2x-4=0

x= -3. x = 4/2

x= 2.

Hence the zeroes of 2x²+2x-12 are -3 & 2.

Answer 2

Answer:

2x^2 + 2x -12 = 0

2x^2 + 6x - 4x - 12 = 0

2x (x + 3) - 4 (X + 3) = 0

(2x - 4) (X + 3) = 0

x = 2

& x = -3
