Question

(5*3-12*2+12x+13)/(x^2-3x+4)​

Answer 1

Answer:

Hello

Step-by-step explanation:

$\frac{5 \times 3 - 12 \times 2 + 12x + 13}{x {}^{2} - 3x + 4} \\ \frac{15 - 24 + 1 + 12x}{x {}^{2} - x + 4x + 4} \\ \frac{ - 9 + 1 + 12x}{x(x - 1) + 4(x - 1)} \\ \frac{ - 8 + 12x}{(x = - 4)(x = 1)} = - 8 + 12x =( x = - 4)(x = 1) \\ - 8 + 12x = x = - 3 \\ 12x = - 3 - 8 = - 11 \\ 12x = - 11 \\ x = \frac{ - 11}{12}$
