Factor by grouping calculator

A quadratic equation can be factored in different ways. One of the methods to factor is by grouping them. This method involves grouping two terms each and then pulling out a common factor out of them. Factor by grouping calculator is the instant tool which can easily help us factor the quadratic equation.

Example 1: Factor the given quadratic expression by grouping: x² + 3x + 2

Given quadratic expression: x² + 3x + 2

Now expand the given quadratic expression by splitting ‘3x’ term in two parts.

‘3x’ can be written as ‘(1 + 2) x’.

Also, the constant term ‘2’ can be written as ‘(1 * 2)’

Hence > x² + 3x + 2 = x² + x + 2x + 2

Now group the first two and last two terms > x(x + 1) + 2(x + 1)

(x + 2)(x + 1) are the factors!

Example 2: Factor the given quadratic expression by grouping: x²+ 2x – 8

Given quadratic expression: x²+ 2x – 8

Now expand the given quadratic expression by splitting ‘2x’ term in two parts.

‘2x’ can be written as ‘(4 - 2) x’.

Also, the constant term ‘-8’ can be written as ‘(4 * -2)’

Hence > x² + 2x – 8 = x² + 4x – 2x - 8

Now group the first two and last two terms > x(x + 4) – 2(x + 4)

(x + 4)(x - 2) are the factors!

I just want you to know how great Brinda has been in tutoring me on probability. She is patient and very knowledgeable in all concepts. I look forward to many more sessions with her. I appreciate her help and the great work that Tutor Pace is doing.

Your tutor has been such an inspiration to me as I have difficulty getting some of the physics concepts down and truly understanding them. She takes the time to fully explain each and every aspect of any problem I might ask for help and always with encouragement and humor.
