-7
The discriminant is -7
2X2+5x-12 4+5x-12 -8+5x 5x-8
D = b²-4ac a=2, b=5, c=4 D=5²-4(2*4) D=25-4(8) D=25-32 D=-7■
2x2 + 10x - 3 The discriminant is defined as b2 - 4ac, so for this function b=10, a=2, and c=-3 So the discriminant is 100-4*2*-3 = 124
-7
Discriminant = 52 - 4 x 2 x (-8) = 89
The discriminant is -7
2X2+5x-12 4+5x-12 -8+5x 5x-8
-7
2x2 - 5x + 12 does not factor. 2x2 - 5x - 12 factors into (2x + 3)(x - 4) 2x2 + 5x - 12 factors into (2x - 3)(x + 4)
D = b²-4ac a=2, b=5, c=4 D=5²-4(2*4) D=25-4(8) D=25-32 D=-7■
It is: 25-4(8*6) = -167
The discriminant is 9.
2x2 + 10x - 3 The discriminant is defined as b2 - 4ac, so for this function b=10, a=2, and c=-3 So the discriminant is 100-4*2*-3 = 124
2X2 + 3X - 4 = 0the discriminant is,b2 - 4ac32 - 4(2)(- 4)9 + 32 = 4141 > 1this means there are two real roots to this equation
52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
