Question

Write g(x) = 40x + 4x2 in vertex form. Write the function in standard form. Factor a out of the first two terms. Form a perfect square trinomial. Write the trinomial as a binomial squared.
g(x) = 4x2 + 40x
g(x) = 4(x2 + 10x)
(10/2)^2= 25
g(x) = 4(x2 + 10x + 25) – 4(25)
g(x) =______ (x +______)2 – _______
Fill the blanks.

Answer 1

g(x)=4x^2+40x
g(x)=4(x^2+10x)
g(x)=4(x^2+10x+25)-4(25)
g(x)=4(x+5)^2-100

the missing numbers that should be filled in the blanks are:
4, 5, 100

Answer 2

Answer:

g(x)= [ 4 ] (x + [ 5 ] )^2 - [ 100 ]
