(x +1)^2-5x(x+3)(x-3)

Use binomial theorem to expand .

Use the distributive property to multiply -5x by x+3.

Use the distributive property to multiply by x-3 and combine like terms.

Combine 2x and 45x to get 47x.

Follow the same steps till and then use the algebraic identity ⇨ a + 2ab + b² = (a + b)²

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
