The given quadratic equation is x^2+x-1/(√2)=0This equation can also be written as √2x^2+√2x+1=0On comparing this equation with ax^2+bx+c=0, we obtain a=√2,b=√2 and c=1∴ Discriminant (D)=b^2-4ac=(√2)^2-4*(√2)*1=2-4√2Therefore, the required solutions are...

To find the time it takes for the object to reach its maximum height, we can use the quadratic formula, where a = -4.9, b = 20, and c = 10. What is the difference between kinematics and dynamics? Kinematics focuses on describing the motion of objects, while dynamics deals with the ...
When Ali throws the ball towards Ben, the equation to model the trajectory of the ball is, y=-0.018x2+0.49x+1.2. (a)In this part of the question, you are asked to consider the graph modelled by the quadratic equation above. ...
Euler‐Lagrange quadratic functional equationquasi‐Banach spacestabilityBy using Aoki‐Rolewicz Theorem on p ‐normalizing a quasi‐normed space, we prove stability results for Euler‐Lagrange quadratic functional equations in quasi‐Banach spaces. These results improve stability results and give the ...
Elementary Algebra-This focuses on topics like real and complex numbers, variables, and other algebraic quantities, along with concepts like their rules of operation and geometric representations. It involves problems for simplifying expressions, solving linear and quadratic equations, and multiplying binomi...
In the main scheme it is for making x the subject and then multiplying both numerator and denominator by √2+1In the alternative it is for squaring both sides to produce a 3TQ and then factorising their quadratic equation to find x. (usual rules apply for solving quadratics)A1: x=6+3...
