Which expression is equivalent to (x2 − 3) − (− 3x2 + 5)?

A) 4x2 − 8
B) 4x2 − 2
C) −2x2 − 2
D) −2x2 − 8

4x2-8

Step-by-step explanation:

This question requires a step by step procedure

Ensure that you don't miss any steps so as to get the right answer

So let's solve the given question

(X2-3)-(-3x2+5)

Let's start by dealing with the bracket first

(X2-3)+3x2-5

X2-3+3x2-5

Collect like terms

X2+3x2-3-5

4x2-8

So the answer is 4x2-8

But in the case where we are asked to solve further we can actually equate the equation to zero

4x2-8=0

4x2=8

Divide both sides by 4

X2=2

Square root both sides

X=√2

But since we are not asked to solve further,our final answer is 4x2-8

I believe this will help you

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
