Question

Please help!:
What are the solutions & x-intercepts? 4x^2=12

Also Give exact and approximate solutions to three decimal places.
y^2-6y+9=64

Answer 1

Find the x intercepts by letting y = 0. They are the roots of the equation 4x^2-12=0

Answer 2

x^2-3=0
x=+-sqrt3=+-1.732

Answer 3

(y-3)^2=64
y-3=+-8
y=-5,11
