Question

How did you simplify each equation
X2 ×10x+9=0

Answer 1

Answer:

$\sqrt[3] \frac{ - 9}{10}$

Step-by-step explanation:

${x}^{2} \times 10x + 9 = 0 \\ {10x}^{3} + 9 = 0 \\ {10x}^{3} = - 9 \\ {x}^{3} = \frac{ - 9}{10} \\ x = \sqrt[3] \frac{ - 9}{10}$

Answer 2

Answer:

By splitting middle term method

X2 +(1 + 9)x + 9 = 0

X2 + 1x + 9x + 9 = 0

X(x + 1) + 9(x+1) =0

(x+9)(x+1) This is correct answer
