Question

x^2-20x+91=0
${x}^{2} - 20x + 91 = 0$

Answer 1

Your Answer ↓↓↓↓↓.

This is a Question from Quadratic Equation and we will solve it through Middle - term splitting .

$x^{2} - 20x + 91 = 0$

$x^{2} - 13 x - 7x +91 =0$

$x(x - 13) -7(x-13)=0$

$(x-7)(x-13) = 0$

then , 
x = 7 
 x = 13

$x {}^{2} - 20x + 91 \\ x {}^{2} - 13x - 7x + 91 \\ x(x - 13) - 7(x - 13) \\ (x - 7)(x - 13) \\ \\now \\ x - 7 = 0 \\ x = 7 \\and \\ x - 13 = 0 \\ x = 13$
