Answer 2

$\color{red}\huge{\underline{\underline{GIVEN\dag}}}$

• ${x}^{2} + x - 20 = 0$

$\color{red}\huge{\underline{\underline{SOLUTION\dag}}}$

$\implies {x}^{2} + 5x - 4x - 20 = 0$

$\implies x(x + 5) - 4(x + 5) = 0$

$\implies (x - 4)(x +5 ) = 0$

$\orange{ \boxed{\therefore x = 4 \: \: or \: \: - 5 }}$

Therefore roots of equation are;

• $x = 4$
• $x = - 5$

HOPE THAT HELPS!!
