WebFind the value of k, for which the quadratic equation 2x 2+kx+3=0 has two real equal roots. Easy Solution Verified by Toppr Given, 2x^2+Kx+3 here it is in the form ax^2+bc+C=0 here a=2, b=K, c=3 if it has two equal roots. then ∆=0 b^2-4ac=0 k^2-4 (2) (3)=0 k^2-24=0 k^2=24 k=√24 k=+2√6 or -2√6 Was this answer helpful? 0 0 Similar questions WebSolving linear simultaneous equations graphically E.g. Solve the pair of simultaneous equations x +y = 6 −3x +y = 2 x + y = 6 − 3 x + y = 2 When we draw the graphs of these two equations, we can see that they intersect at ( 1, 5 ). So the solution to the simultaneous equations is: x = 1 and y = 5 dstv bouquets zambia
