WebFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Web4x 2 − 9 = (2x) 2 − (3) 2 And that can be produced by the difference of squares formula: (a+b) (a−b) = a 2 − b 2 Where a is 2x, and b is 3. So let us try doing that: (2x+3) (2x−3) = (2x) 2 − (3) 2 = 4x 2 − 9 Yes! So the factors of 4x2 − 9 are (2x+3) and (2x−3): Answer: 4x 2 − 9 = (2x+3) (2x−3) How can you learn to do that?
Web2 de nov. de 2016 · Explanation: This is not factorable normally. We can see this since x2 −2x + 1 is a perfect square, so it touches the x-axis at a single root. Adding 1 to this produces x2 −2x + 2, and raises the graph of y = x2 − 2x +1 one upwards, meaning it no longer touches the x-axis, so it has no real roots. However, we can find its imaginary … Web10 de dic. de 2015 · Cymath gives me $(x-\frac{1+\sqrt{5}}{2})(x-\frac{1... Stack Exchange Network.
