What is a trinomial?

Back

A trinomial is a polynomial with three terms, typically in the form ax^2 + bx + c.

Front

How do you factor a trinomial?

Back

To factor a trinomial, find two numbers that multiply to 'c' (the constant term) and add to 'b' (the coefficient of the x term).

Front

Factor the trinomial: x^2 - 8x + 15

Back

(x - 5)(x - 3)

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

Write the equation of a line with a slope of -1/2 and a y-intercept of -3.

Back

y = -\frac{1}{2}x - 3

Front

What does f(0) represent in a function?

Back

f(0) represents the y-value of the function when x is 0, also known as the y-intercept.

Front

Calculate f(0) for the function y = 2x - 2.

Back

f(0) = 2(0) - 2 = -2.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line, represented by the equation y = mx + b.

Front

Solve for x and y: 2x - 3y = -1 and y = x - 1.

Back

(4, 3) is the solution.

Front

What is the y-intercept of the equation y = 3x + 16?

Back

The y-intercept is 16.
