Question

Tramsform the given quadratic functions into the form y=a(x-h)^2+k

1. y=x^2-2x-10
2. y=2x^2-3x+1​

Answer 1

Step-by-step explanation:

y =2x^2 + 24x + 12

y = 2[x^2 + 12x + 6]

= 2[x^2 + 12x + (12/2)^2 -(12/2)^2 + 6]

= 2[(x+ 6)^2 - 30]

y = 2(x + 6)^2 -60 <==> y = a(x - h)^2 + k

a = 2

h = -6

k = -60.
