Question

what are the root of the quadratic equation 2x square +6= -7​

Answer 1

Answer:

2x2 – x – 6 = 0

2x2 – 4x + 3x – 6 = 0

2x(x – 2) + 3(x – 2) = 0

(x – 2) (2x + 3) = 0

x – 2 = 0 or 2x + 3 = 0

x = 2 or 2x = -3

x = 2 or x = -3/2

Hence, 2 and -3/2 are the roots of the given equation.

Answer 2

Answer:

2x2 – x – 6 = 0

2x2 – 4x + 3x – 6 = 0

2x(x – 2) + 3(x – 2) = 0

(x – 2) (2x + 3) = 0

x – 2 = 0 or 2x + 3 = 0

x = 2 or 2x = -3

x = 2 or x = -3/2

Hence, 2 and -3/2 are the roots of the given equation.
