i need help for an algebra test tomorrow please explain step by step
write the given equation in the form y= a (x-h)^2 + k: y=2x^2+4x-3
thank you very much everyone, and please excuse my poor english!

write the given equation in the form y= a (x-h)^2 + k:
y=2x^2+4x-3
y/2=x^2+2x-3/2
Let's complete the square:
y/2=x^2+2x+1 -3/2 - 1
y/2=(x + 1)^2 -3/2 - 1
y/2=(x + 1)^2 -5/2
y = 2(x + 1)^2 - 5
a = 2, h = -1, k = -5
y=2x^2+4x-3
y/2=x^2+2x-3/2
Let's complete the square:
y/2=x^2+2x+1 -3/2 - 1
y/2=(x + 1)^2 -3/2 - 1
y/2=(x + 1)^2 -5/2
y = 2(x + 1)^2 - 5
a = 2, h = -1, k = -5

y= a (x^2-h^2)+k
y= ax^2-ah^2+k
y= ax^2-ah^2+k
