-7

-7 therefore the quadratic equation has no real roots

2X2+5x-12 4+5x-12 -8+5x 5x-8

A quadratic polynomial.

b2 - 4ac (whatever that 4's sign is it is positive when squared ) (4)2 - 4(2)(- 9) 16 + 72 = 88 ===============Two real roots.

Discriminant = 52 - 4 x 2 x (-8) = 89

-7 therefore the quadratic equation has no real roots

52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.

2x2 - 5x + 12 does not factor. 2x2 - 5x - 12 factors into (2x + 3)(x - 4) 2x2 + 5x - 12 factors into (2x - 3)(x + 4)

2X2+5x-12 4+5x-12 -8+5x 5x-8

A quadratic polynomial.

x3 + 2x2 + 5x + 4 = (x + 1)(x2 + x + 4)

b2 - 4ac (whatever that 4's sign is it is positive when squared ) (4)2 - 4(2)(- 9) 16 + 72 = 88 ===============Two real roots.

If you mean: 4x squared+7x+4 then the discriminant is -15

A Quadratic statement

2X2 + 3X - 4 = 0the discriminant is,b2 - 4ac32 - 4(2)(- 4)9 + 32 = 4141 > 1this means there are two real roots to this equation
