Question

${x}^{2} - 2x - 143$
​

Answer 1

Answer:

$x{}^{2} - 2x - 143$

$x {}^{2} - (13 - 11)x - 143$

$x {}^{2} - 13x + 11x - 143$

$x(x - 13) + 11(x - 13)$

$(x + 11)(x - 13$

Answer 2

Step-by-step explanation:

x^2-2x-143=0

x^2-13x+11x-143=0

x(x-13)+11(x-13)=0

thus

x+11=0

x=-11

also

x-13=0

x=13
