Simplify (x^2+1)/ (x^2-1) x2 + 1 x2 − 1 x 2 + 1 x 2 - 1. Rewrite 1 1 as 12 1 2. x2 +1 x2 −12 x 2 + 1 x 2 - 1 2. Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = ( a + b) ( a - b) where a = x a = x and b = 1 b = 1. x2 +1 (x+1)(x−1) x 2 + 1 ( x + 1) ( x - 1)How do you solve x2 + x + 1 = 0? Algebra Quadratic Equations and Functions Comparing Methods for Solving Quadratics 1 Answer KillerBunny Apr 11, 2015 You can use the standard formula which allows you to solve any quadratic equation, which is x1,2 = −b ± √b2 − 4ac 2aStep 1 : Equation at the end of step 1 : x • (x - 1) • (x - 2) = 0 Step 2 : Equation at the end of step 2 : x • (x - 1) • (x - 2) = 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.Solve for x x^2-x-4=0. x2 − x − 4 = 0 x 2 - x - 4 = 0. Use the quadratic formula to find the solutions. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. Substitute the values a = 1 a = 1, b = −1 b = - 1, and c = −4 c = - 4 into the quadratic formula and solve for x x. 1±√(−1)2 −4 ⋅(1⋅−4) 2⋅1 1 ± ( - 1) 2 - 4 ⋅ ( 1 ... Check whether the vectors a = {1; 1; 1}, b = {1; 2; 0}, c = {0; -1; 2} are linearly independent. Solution: Calculate the coefficients in which a linear combination of these vectors is equal to the zero vector. x 1 a + x 2 b + x 3 c 1 = 0. This vector equation can be written as a system of linear equationsSolve for x x^2-x-4=0. x2 − x − 4 = 0 x 2 - x - 4 = 0. Use the quadratic formula to find the solutions. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. Substitute the values a = 1 a = 1, b = −1 b = - 1, and c = −4 c = - 4 into the quadratic formula and solve for x x. 1±√(−1)2 −4 ⋅(1⋅−4) 2⋅1 1 ± ( - 1) 2 - 4 ⋅ ( 1 ...Algebra. Solve for x 2x-1=0. 2x − 1 = 0 2 x - 1 = 0. Add 1 1 to both sides of the equation. 2x = 1 2 x = 1. Divide each term in 2x = 1 2 x = 1 by 2 2 and simplify. Tap for more steps... x = 1 2 x = 1 2. The result can be shown in multiple forms.If you drag x along the violet plane, the product Ax is always equal to b. This is what it means for the plane to be the solution set of Ax = b. In the above Example 2.4.6, the solution set was all vectors of the form. x = (x1 x2 x3) = x2(1 1 0) + x3(− 2 0 1) + (1 0 0).-2x+2y-z = 1 First we rearrange the equation of the surface into the form f(x,y,z)=0 z=x^2-2xy+y^2 :. x^2-2xy+y^2-z = 0 And so we define our surface function, f, by: f(x,y,z) = x^2-2xy+y^2-z In order to find the normal at any particular point in vector space we use the Del, or gradient operator: grad f(x,y,z) = (partial f)/(partial x) hat(i) + (partial …x^{2}+3x+1=0. en.
