Question

if x=3 is one root of quadratic polynomial p(x)=x
${2}^{2}$
-5x+6 then find the other root

Answer 1

${x}^{2} - 5x + 6 \\ {x}^{2} - 3x - 2x+ 6 \\ x(x - 3) - 2(x - 3) = 0 \\ (x - 3)(x - 2) = 0 \\ x - 3 = 0 \\ x = 3 \\ x - 2 = 0 \\ x = 2 \\ other \: root \: is \: 2$

Answer 2

these are the two roots of x ..,......
