Bundle: College Algebra, 7th + DVD + Enhanced WebAssign Homework Printed Access Card for One Term Math and Science (7th Edition) Edit edition Jul 25, 2010 · Dont be confused, 25x^2 - 4 = 0. x is the squared variable not 25. If it was 25 we would have the ^2 coming right after 25, i.e, 25^2. Therefore this is how we solve the equation Question 190654: Factor the binomial 25x^2-121 Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website! Answer to Factor.

Since both terms are perfect squares, factor using the difference of squares formula, where and . That depends on what numbers we are using. This binomial is irreducible (cannot be factored) over the real numbers. If we are working with polynomials over the complex numbers, then this is a difference of squares and can be factored using -49 = (7i)^2, so 25x^2 + 49 = 25x^2 -(-49) =(5x+7i)(5x-7i) One Root at {x,y}={-1.40, 0.00} Note that the root coincides with the Vertex and the Axis of Symmetry coinsides with the line x = 0 . Solve Quadratic Equation by Completing The Square 4.2 Solving 25x 2 +70x+49 = 0 by Completing The Square . Divide both sides of the equation by 25 to have 1 as the coefficient of the first term : x 2 +(14/5)x+(49 Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. (t + 7) • (t - 7) = 0 Step 2 : Theory - Roots of a product : 2.1 A product of several terms equals zero.

## Simplifying 25x 2 + kx + 49 = 0 Reorder the terms: 49 + kx + 25x 2 = 0 Solving 49 + kx + 25x 2 = 0 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right.

Add '49' to each side of the equation. -49 + 49 + 25x 2 = 0 + 49 Combine like terms: -49 + 49 = 0 0 + 25x 2 = 0 + 49 25x 2 = 0 + 49 Combine like terms: 0 + 49 = 49 25x 2 = 49 … 5 2 x 2 - 49 = 0 Step 2 : Trying to factor as a Difference of Squares : 2.1 Factoring: 25x 2-49 Theory : A difference of two perfect squares, A 2 - B 2 can be factored into (A+B) • (A-B) Proof : (A+B) • (A-B) = A 2 - AB + BA - B 2 = A 2 - AB + AB - B 2 = A 2 - B 2 Note : AB = BA is the commutative property of multiplication.
