WebThe quadratic equation having roots that are reciprocal to the roots of the equation ax 2 + bx + c = 0, is cx 2 + bx + a = 0. The given quadratic equation is 2x 2 + 9x + 7 = 0. Hence the required equation having reciprocal roots is 7x 2 + 9x + 2 = 0. Method 2: From the given equation, α + β = -9/2 and α β = 2/7. WebApr 15, 2016 · It is not difficult to find functions that have no roots: for any function f(x), g(x) = f(x) + 1 has no roots. For any function g(x) that has no real roots, and any function f(x), the function g(f(x)) shouldn't have any real roots. You can encounter a little bit of a problem with function domains though.

WebSince the second equation is equal to y, we will replace the y in the first equation with the square root of two times x minus 5. Now we have one equation, with one variable.
