Question

What are the zeros of h (x) = 2x2 – 8x – 10?

Answer 1

Answer:

x=5, -1

Step-by-step explanation:

set the equation equal to 0: 2x^2-8x-10=0

divide both sides by 2 to get x^2-4x-5=0

next factor your new equation to get (x+1)(x-5)

set those equal to zero

now you have x+1=0 and x-5=0

finally, solve for x by subtracting 1 and adding 5

now you have your answer x= 5 and -1
