A = 9, B = - 1, C= 56

obtain the equation in ' slope-intercept form'

y = mx + c → ( m is the slope and c the y- intercept)

calculate m using the ' gradient formula'

m = (- 7 - 2)/(- 7 + 6) = (-9)/(-1) = 9

partial equation is y = 9x + c

to find c substitute either of the 2 points into the equation.

using (- 6, 2) then

2 = - 54 + c ⇒ c = 2 + 54 = 56

y = 9x + 56 → slope-intercept equation

subtract y from both sides

0 = 9x - y + 56 → general form

with A = 9, B = - 1, C = 56

create a perfect square trinomial that can be factored using special patterns. Factor the trinomial and show all work for full c
Lyrx [107]

Answer: 4x^2+12x+9


Step-by-step explanation:

A perfect square trinomial is written as ax^2+bx+c, where

first term ax^2 = square of first term of binomial

second term=bx=twice the product of both terms of binomial.

and third term 'c'=square of last term of binomial

Thus to create a perfect  square trinomial put 'a' and 'c' a square number

Let a=4 and c=9

The required trinomial will be

4x^2+12x+9

=(2x)^2+2(2x)(3)+3^2\\=(2x+3)^2.......\text{[using pattern}(a+b)^2=a^2+2ab+b^2]\\=(2x+3)(2x+3)
