What are the x-intercepts of the equation y=x²+11x+10?

Back

The x-intercepts are the points where the graph crosses the x-axis. For the equation y=x²+11x+10, the x-intercepts are -10 and -1.

Front

Simplify: (3x - 5)(4x² - 2x - 3)

Back

The simplified form is 12x³ - 26x² + x + 15.

Front

Solve for y: -5 - 7y = -20y + 34

Back

y = 3.

Front

Simplify: 2x⁴(3x³ - x² + 5x)

Back

The simplified expression is 6x⁷ - 2x⁶ + 10x⁵.

Front

What is another word for zeros in a function?

Back

Roots.

Front

Define the term 'quadratic equation'.

Back

A quadratic equation is a polynomial equation of degree 2, typically in the form ax² + bx + c = 0.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation.

Front

Explain the concept of 'factoring' in algebra.

Back

Factoring is the process of breaking down an expression into simpler components, or factors, that when multiplied together give the original expression.

Front

What is the difference between a linear equation and a quadratic equation?

Back

A linear equation has a degree of 1 and graphs as a straight line, while a quadratic equation has a degree of 2 and graphs as a parabola.

Front

What does it mean for two expressions to be equivalent?

Back

Two expressions are equivalent if they have the same value for all values of the variable.
