Question

Can the quadratic polynomial x ^2+kx+k have equal zeroes for some integer K > 1?​

Answer 1

hello buddy

here's your answer

the formula to find equal zeros of an equation is

${b}^{2} - 4ac = 0$

here b=k

a=1

and c=k

thus

${k}^{2} - 4 \times 1 \times k = 0$

which gives

${k}^{2} - 4 {k} = 0$

which gives

${k(k-4)} =0$

thus ${k=4} {or} {k=0}$

which shows that k can be greater than 1 as k=4 greater than 1

hope it helps
