${x}^{2} - 3x - 10 = 0$
factorisation
x2-3x-10 =0
​

Answer 1

Answer:

$x {}^{2} - 3x - 10 \\ {x}^{2} - 5x + 2x - 10 \\ x(x - 5) + 2(x - 5) \\ (x - 5) \: and \: (x + 2) \\ x = 5 \: and \: x = - 2$

Answer 2

Answer:

$\green{(x+2)(x-5)=0}$

Explanation:

$splitting \: the \: middle \: term$

$x {}^{2} - 3x - 10 = 0$

$x {}^{2} - 5x + 2x - 10 = 0$

$x(x - 5) + 2(x - 5) = 0$

$(x + 2)(x - 5) = 0$

$\blue{Hence}$

$\green{solved}$
