Question

$x {}^{2} - 32x - 105$
​

Answer 1

${x}^{2} - 32x - 105 = 0 \\ {x}^{2} - 32x = 0 + 135 \\ {x}^{2} - x = \frac{135}{32} = 4.21.. \\ {x}^{2} - x = 4.21 \\ {x}^{2} = \sqrt{ - 4.21} \\ x = 2.051...$

Answer 2

$\huge\boxed{\underline{\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{..}}}}$

$\longmapsto \sf {x}^{2} - 32x + 105$

By splitting middle term

$\longmapsto \sf {x}^{2} - 35x + 3x - 105$

$\longmapsto \sf x(x - 35) + 3(x - 35)$

$\longmapsto \sf(x + 3)(x - 35)$
