Implify the expression –3(x + 3)2 – 3 + 3x. What is the simplified expression in standard form?
1 answer:
<span>–3(x + 3)^2 – 3 + 3x
</span>First, we expand the term to be squared:(x + 3)^2 = x^2 + 6x + 9So the expression becomes-3(x^2 + 6x + 9) - 3 + 3x-3x^2 - 18x - 27 - 3 + 3x-3x^2 - 15x - 30

Step-by-step explanation:
f(x) × g(x)
= (x2 + 5x )× (3x2 -4x )
=3x4 + 15x3 - 4x3 -20x2
3x^4 + 11 x3 - 20x2
The ratio of the areas:
225 : 36 = 15² : 6²
The ratio of their corresponding sides:
15 : 6 = 5 : 2
