Answer:
All the answers are given below.
Step-by-step explanation:
(i) (x+3)(x-3) =x² -3² =x² -9 {Since (a+b)(a-b) =a² -b²}
(ii) (x²-3)(x²+3) =(x²)² -3² =
{Since (a+b)(a-b) =a² -b²}
(iii) 
(iv) (x-3)(x²-9)(x+3) =(x²-9)(x²-9)=(x²-9)²=
{Since, (a-b)² =a²-2ab+b²}
(v) (x²+y²)(x²-y²) = (x²)² -(y²)² =
(vi) (x²+y²)² =
{Since (a+b)² =a²+2ab+b²}
(vii) (x-y)²(x+y)² =(x²-y²)² =
{Since (a-b)² =a²-2ab+b² and (a+b)(a-b) =a²-b²}
(viii) (x-y)²(x²+y²)²(x+y)² =(x²+y²)²(x²-y²)² =

Answer:
x = -2
Step-by-step explanation:
Distribute: 18x + 24 = 4x - 4
Subtract 4x from both sides: 14x + 24 = -4
Subtract 24 from both sides: 14x = -28
Divide both sides by 14: x = -2
Answer:
1st add 2x+25 then 3x+1 then 5x-2 what answer you get thats the answer of this question......
pleae follow me and give me a thanks also mark me brai liest. i will mark u too.....
I'm taking the liberty of editing your function as follows: <span>w=4r^2+6s^2, where I use " ^ " to indicate exponentiation.
The partial of w with respect to r is 8r. That with respect to s is 12s.</span>
