Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Question 280547: Solve 25x^2 + 49 = 0 This is what I have: 25x^2 + 49 - 49 = 0 + -49 25x^2 = -49 25x^2/25 = -49/25 x^2 = -1.96 x^2 + 1.96 = 1.96 + - 1.96 x^2 + 1.96 = 0 Therefore a solution cannot be determine. Am I correct or is the solution x^2 + 1.96 = 0? Found 2 solutions by Alan3354, Earlsdon: x 2 - 25x = x • (x - 25) Equation at the end of step 2 : x • (x - 25) = 0 Step 3 : Theory - Roots of a product : 3.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero.

Factor the expression by grouping. First, the expression needs to be rewritten as x^{2}+ax+bx+25. To find a and b, set up a system to be solved.

What we have here is called a "Difference of Two Squares", which can be solved using the following formula: Trying to factor as a Difference of Squares : 0.1 Factoring: 25x 2 - 49 Theory : A difference of two perfect squares, A 2 - B 2 can be factored into (A+B) • (A-B) (t + 7) • (t - 7) = 0 Step 2 : Theory - Roots of a product : 2.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. We shall now solve each term = 0 separately In other words, we are going to solve as many equations as there are terms in the product x 2 - 25x = x • (x - 25) Equation at the end of step 2 : x • (x - 25) = 0 Step 3 : Theory - Roots of a product : 3.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero.

GCD of x^4+2x^3-9x^2+46x-16 with x^4-8x^3+25x^2-46x+16; In such cases, the polynomial is said to "factor over the rationals." Factoring is a useful way to find rational roots (which correspond to linear factors) and simple roots involving square roots of integers (which correspond to quadratic factors). 28/06/2011 25x^2 -49=0 what is x.
