(7x^2-16)/(x^2-2x) solve by using partial fraction decomposition. i cant figure out how to do this because after i split up the bottom the A and B dont end up having an x^2 in order to equal the numerator of the original fraction. so confused!
Find the values of b such that the system has one solution. x^2 + y^2 = 36 y= x+b and then they give me an answer box b=_________ (smaller value) b=_________ (larger value) i have absolutely no idea how to even begin this and what they are asking. could some please help and ex...
yes but i still dont get the answer!!!
Use matrices to solve the system. (If the system has infinitely many solutions, express your answer in terms of c, where x = x(c), y = y(c), and z = c. If the system has no solution, enter NONE for each answer.) 5x+2y-z=2 x-2y+2z= -1 3y+z= -17 ive done tons of these but this o...
Find an equation of the cubic polynomial f(x) = ax3 + bx2 + cx + d that passes through the given points. P(0,-4) Q(1,-8) R(-1,-8) S(2,-2) Ive tried this every which way and i cant seem to get any of these..i know your supposed to plug it in and all but its just not working for...
A polynomial f(x) with real coefficients and leading coefficient 1 has zeros 6 + 4i, -5 + i and degree 4. Express f(x) as a product of quadratic polynomials with real coefficients that are irreducible over R. ive done this problem every which way i could. specifically i unders...
The midpoint of line AB has coordinates of (5,-1). If the coordinates of A are (2,-3), what are the coordinates of B? Any help is appreciated!
