Amira is solving the equation x2 – 6x = 1. which value must be added to both sides of the equation to make the left side a perfect-square trinomial? –9 8 9 36

we know that

The perfect square trinomial in this problem is equal to

in this problem we have

Let

so

therefore

the answer is

To make the left side a perfect-square trinomial must be added to both sides of the equation the value of

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
