Question

5x^2 + 10x . find zeroes.
step by step

Answer 1

Step-by-step explanation:

$5 {x}^{2} + 10x = 0 \\ 5( {x}^{2} + 2x) = 0 \\ {x}^{2} + 2x = 0 \\ x(x + 2) = 0 \\ x = 0 \: \: or \: \: \: x + 2 = 0 \\ x = 0 \: \: \: or \: \: \: x = - 2$

Answer 2

Answer:

The correct answer is x=0, -2

Step-by-step explanation:

Given: 5x^2 + 10x

To find: find zeroes

open the equation,

5(x^2+2x)=0

put x as a common,

x^2+2x=0

x(x+2)=0

x=0,

x+2=0

x=-2

the final answer is x=0,-2
