How do you factor 2x^2 - 5x - 3?

Update:

JC are you sure?

  • Use factoring decomposition. Split -5x into -6x and x since -6 and +1 yields the product of -6 and the sum of -5...

    2x² - 6x + x - 3

    Factor like terms to get..

    (2x² - 6x) + (x - 3)

    = 2x(x - 3) + 1(x - 3)

    Finally, we have..

    (x - 3)(2x + 1) [Group the common factors of x - 3 and collect the terms!]

    I hope this helps!

  • Multiply 2 by -3. That give us -6.

    Find two numbers who when multiplied give us -6 but at the same time also adds up to -5.

    -6 and +1 are the only integers that work.

    Now, divide 2 by each of these numbers.

    2 / -6 = 1 / -3

    2 / 1 = 2 / 1

    Then use these expressions to write the newfactored expression.

    (x - 3) (2x + 1)

  • (2x - 1) (x - 2)

    If the question is 2x^2 - 5x -3 = 0

    then x = 1/2 or 2

  • (2x+1)(x-3)

  • use the quadratic formula
