What is the vertex form of #7y=(x − 3)(4x + 2) #? Algebra Quadratic Equations and Functions Vertex Form of a Quadratic Equation 1 Answer Anjali G Jun 6, 2017 #y = 4/7(x- 5/4)^2 - 7/4# Explanation: #7y = (x-3)(4x+2)# #y = 1/7 * 4 * (x-3)(x+ 1/2 )# #y = 4/7 (x^2-5/2 x - 3/2)# #y = 4/7 [(x- 5/4)^2 - 49/16]# #y = 4/7(x- 5/4)^2 - 7/4# Answer link Related questions What is the Vertex Form of a Quadratic Equation?
