Question

Solve the following equation by factorization method x
$x ^{2} + x - 20 = 0$
​

Answer 1

Step-by-step explanation:

x^2 + x +-20=0

x^2 + 5x-4x-20=0

x(x+5)-4(x+5)=0

(x-4)(x+5)=0

x-4=0/(x+5)

x-4=0

x=4

Answer 2

Step-by-step explanation:

x²+x-20=0

x²+(5-4)x-20=0

x²+5x-4x-20=0

x(x+5)-4(x+5)=0

(x+5)(x-4)=0

x+5=0. x-4=0

x= -5. x=4

x= -5,4
