A. what is the sum of the squares of the roots of $x^2 - 5x - 4 = 0$? b. one root of $x^2 + 12x + k = 0$ is twice the other root. find $k.$ c. what is the sum of the roots of the quadratic $4x^2 - 4x - 4$? d. jimmy is trying to factor the quadratic equation $ax^2 + bx + c = 0.$ he assumes that it will factor in the form \[ax^2 + bx + c = (ax + b)(cx + d),\]where $a,$ $b,$ $c,$ and $d$ are integers. if $a = 4,$ and jimmy wants to find the value of $a,$ what are the possible values he should check, in order to find $a$? e. brandy is trying to factor the quadratic $3x^2 - x - 10.$ she starts by assuming that the quadratic factors as \[3x^2 - x - 10 = (x + b)(3x + d),\]for some integers $b$ and $d.$ after some work, brandy successfully factors the quadratic. find the ordered pair $(b,d).$

Someone , i do not understand. what is the quadratic function that is created with roots -10 and -6 and a vertex at (-8, -8)? what is the quadratic function that is created with roots at 2 and 4 and a vertex at (3, 1)? i've actually been trying to figure this out for days, but every time i think i have the right answer and understand how to form the quadratic function, i double check it on a calculator and it doesn't make sense. could someone me out and explain this to me?

Write a function for computing the roots using the following function header: int compute_roots(double a, double b, double c, double& x1, double& x2) the arguments a, b, c are the coefficients of the quadratic equation, and x1 and x2 are possible computed roots of the equation (depending on the return value). the return value of this function could be one of the numbers: 0 == no roots 1 == one root 2 == two real roots 3 == infinite number of roots 4 == no real roots you should save the return value in a variable, say, nroots and use it later in a switch statement switch(nroots). do not include any input or output statement inside all input/output statements should be in main() only. (b) test your function in main() for five different quadratic equations. use the included flow chart when writing the function.
