Question

Verify whether 2 and -3/2 are the roots of the quadratic equation 2x2-x-6=0

Answer 1

Step-by-step explanation:

2x2-x-6

2x2-4x+3x-6

2x+3 x-2

x=-3÷2. x=2

Answer 2

Answer:

Because of the Quadratic root formula, we can discover that x=[-b±√(b²-4ac)]÷(2a), so we can get: [1±√(1--24)]/4=[1±5]/4, so the answer is 1.5 and -1
