Which of the following trinomials is equivalent to the square of the binomial x-3?
(1) 2x+6
(3) x² - 6x-9
(2) x +9
(4) x2 - 6x+9

(4) x2 - 6x+9

Step-by-step explanation:

only because it  makes more sense.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

there is no grid
