Solve kx^2+ (2k+1)x+k-1=0 | Microsoft Math Solver Solve math equations with Math Assistant in OneNote to help you reach solutions quickly Use the distributive property to multiply 2k+1 by x Subtract x from both sides Anything subtracted from zero gives its negation Dividing by x^ {2}+2x+1 undoes the multiplication by x^ {2}+2x+1
Solve =x^2+2 (k-1)x+k^2+4=0 | Microsoft Math Solver You only care about the larger of the two roots - the sign of the smaller root is irrelevant So apply the quadratic formula to get the larger root only, which is \frac{-2(k-1)+\sqrt{4(k-1)^2-4(k+5)}}{2} = -k+1+\sqrt{k^2-3k-4}
Solve kx^2-2 (k+1)x+ (k+2)=0 | Microsoft Math Solver What is the value of k if the equation x^2-3 (k+1)x + k^2=0 has equal roots? Let the equal (repeated) root = r Then the equation is (X - r)^2 = 0 Expanding, we get X^2 - 2rX + r^2 = 0 Equating coefficients of like powers of X, we get r^2 = k^2 and 2r = 3 (k + 1) r = ± k
[FREE] Find the value of k for the quadratic equation x^2 - 2(k+1)x + k . . . To find the value of k for which the quadratic equation has real and equal roots we can use the Discriminant method The formula for Discriminant is D=b²-4ac, and for the roots to be real and equal, D must be equal to zero Solving this equation we can find the required value of k
