Question

Find the zeros of the function h(x) = x2 +4x by factoring.
What is the smallest zero of the function? Enter a number only.

Answer 1

x(x+4)

Answer 2

-4

Answer 3

x=-4 and x=0

Answer 4

We have
\[h(x)=x^2+4x\]
We have to find values of x for which h(x) is zero
Let' put h(x)=0
\[0= x^2+4x\]
\[x^2+4x=0\]
\[x(x+4)=0\]
so the zeroes are x=0 and x=-4
The smaller one is your answer
