Question

X2squared plus 5X +6 squad equals 20

Answer 1

Answer:

x^2+5x+6=20

=> x^2+5x+6-20=0

=> x^2+5x-14=0

=> x^2+7x-2x-14=0

=> x(x+7)-2(x+7)=0

=> (x+7)(x-2)=0

=> x+7=0

=> x= -7

again, x-2=0

=> x=2

so, x= -7 , 2

Answer 2

Step-by-step explanation:

$x {}^{2} + 5x + 6 = 20$

$x(x + 5) + 6 = 20$

$x(x + 11) = 20$

$x {}^{2} = 20 - 19$

$x {}^{2} = 1$

$\sqrt{x {}^{2} } = \sqrt{1}$

$x = 1$
