Or,(x−1)(x−2)=0(x-1)(x-2)=0 Hence,roots are; 1 and 2 Question 4: The sum of reciprocals of Rehman’s ages, (in years) 3 years ago and 5 years from now is 1/3. Find his present age. Answer:Let us assume, Rehman’s present age = x ...
Quadratic Equations can be factored Quadratic Formula: x = −b ±√(b2 − 4ac) 2a When the Discriminant (b2−4ac) is: positive, there are 2 real solutions zero, there is one real solution negative, there are 2 complex solutionsMath...
The equation yields two answers: t = -20 and t = 30. Since negative time has no physical meaning, t = 30 is the only valid solution. Thus, it takes30working days before the cost analyst needs to allocate more resources to fund the project. A few simple facts that you should know Di...
Quadratic Equations: Whenever we are given a quadratic equation, we can expect to find two zeros or roots which are basically values, which when substituted to the independent variable will result to zero. Whenever we have two distinct roots, we can be certain that the graph interse...
Why do you use square roots to solve quadratic equations? Because it's part of the quadratic equation formula in finding the roots of a quadratic equation. Why is the quadratic formula useful? The Quadratic Equation is useful because you can't factorevery equation, so you use the quadratic ...
