Here are the solutions for the expressions you provided:

Part 1· 2 steps

Simplifying the expression x2−3x−4x^2 - 3x - 4

  1. Identify the coefficients of the quadratic expression.

    The expression is in the form ax2+bx+cax^2 + bx + c, where a=1a=1, b=−3b=-3, and c=−4c=-4.

  2. Factor the quadratic expression.

    We need two numbers that multiply to cc (which is -4) and add up to bb (which is -3). These numbers are -4 and 1.

    x2−3x−4=(x−4)(x+1)x^2 - 3x - 4 = (x-4)(x+1)

    The factored form of the expression is (x−4)(x+1)\boxed{(x-4)(x+1)}.

Part 2

x=0x=0

Solving the equation −4x=x−4x-4x = x - 4x

  1. Simplify the right side of the equation.

    Combine the like terms on the right side:

    −4x=x−4x-4x = x - 4x −4x=(1−4)x-4x = (1-4)x −4x=−3x-4x = -3x
  2. Isolate xx by moving all terms containing xx to one side.

    Add 3x3x to both sides of the equation:

    −4x+3x=−3x+3x-4x + 3x = -3x + 3x −x=0-x = 0
  3. Solve for xx.

    Multiply both sides by -1:

    (−1)(−x)=(−1)(0)(-1)(-x) = (-1)(0) x=0x = 0

    The solution to the equation is x=0\boxed{x=0}.
