Simplify the expression: √98a^20c^15

Back

7a^{10}c^7√2c.

Front

Use the quadratic formula to solve the equation: 2x^2 + 2x - 12 = 0.

Back

The solutions are x = 2 and x = -3.

Front

Does the equation Y = -3x^2 + 7x - 2 open up or down?

Back

The parabola opens down.

Front

Simplify the expression: (2x + 5y - z) + (-6x - 4y + 7z)

Back

The simplified expression is -4x + y + 6z.

What does the discriminant tell you about the roots of a quadratic equation?

Back

If the discriminant (b^2 - 4ac) is positive, there are two real roots; if zero, one real root; if negative, no real roots.
