Question

Learning Task 3. Transform the quadratic function defined by y = ax2 +bx+
c into the form
y = a(x - h)2 + k.
1. y= x²-6x-3​

Answer 1

Answer:

y=y=(x-3)^2-12

Step-by-step explanation:

y=1.x-2.3.x-3

add 12 and subtract 12 from the above

y=1.x-2.3.x-3+12-12

it was changed to

y=(1.x-2.3.x+9)-12

it looks like expansion of (x-a)^2=x^2-2ax+a^2 so,

y=(x-3)^2-12
