Factoring Trinomials a = 1

Front

What is a trinomial?

Back

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

Front

What does it mean to factor a trinomial?

Back

Factoring a trinomial involves rewriting it as a product of two binomials.

Front

What is the standard form of a trinomial?

Back

The standard form of a trinomial is ax^2 + bx + c, where a, b, and c are constants.

Front

What is the first step in factoring a trinomial when a = 1?

Back

Identify two numbers that multiply to c and add to b.

Front

Factor the trinomial: x^2 + 5x + 6

Back

(x + 2)(x + 3)

Front

What is the relationship between the roots of a trinomial and its factors?

Back

The roots of a trinomial are the values of x that make the trinomial equal to zero, and they correspond to the values that make each binomial factor equal to zero.

Front

How do you check if your factorization is correct?

Back

Multiply the binomials back together to see if you obtain the original trinomial.

Front

Factor the trinomial: x^2 - 7x + 10

Back

(x - 2)(x - 5)

Front

What is the significance of the leading coefficient in a trinomial?

Back

The leading coefficient (a) affects the shape and direction of the parabola represented by the trinomial.

Factor the trinomial: x^2 + 4x + 4

Back

(x + 2)(x + 2) or (x + 2)^2
