Which is a Quadratic Equation !In "Standard Form" it looks like:−5t2 + 14t + 3 = 0It looks even better when we multiply all terms by −1:5t2 − 14t − 3 = 0Let us solve it ...There are many ways to solve it, here we will factor it using the "Find two numbers ...
And the mathematical relationship that describes it is a quadratic equation. Equation of Motion When you throw a ball, its motion through the air is usually described as freefall, which means the only force acting on it is the force of gravity. (We tend to ignore other forces caused by ...
According to the problem, coefficients of the required quadratic equation arereal and its one root is -2 + i.We know in a quadratic with real coefficients imaginary roots occur inconjugate pairs).Since equation has rational coefficients, the other root is -2 - iNow, the sum of the roots ...
