Question

Solve the equation x^2 + 5x = 0.

A) x = 0, –5
B) x = 0, 5
C) x = 1, –5
D) x = 1, 5

Answer 1

Try factoring out an x, what are you left with?

Answer 2

x^2 + 5x = 0.
taking common
x(x+5)=0
x= 0
x= -5

Answer 4

i think its 1.5

Answer 5

Annas you noob.

Answer 6

quadratics are of the form ax^2 + bx + c and can be factored into two binomials (x + f)(x + g). in this equation c = 0 so that means f or g must be 0; e.g., one solution is 0.
x(x + g) = ax^2 + bx + c
x(x + g) = x^2 + 5x
x(x + 5) = x^2 + 5x

x(x + 5) = 0
by the zero product property x + 5 has to be 0 or x = 0, so solve x + 5 = 0 to get your answer

Answer 7

B) x = 0, 5
