Answer:
i dont know im wondering to o-o
Step-by-step explanation:
To evaluate the expression we proceed as follows;
(7x³-16x+8)-(4x³-6x²+8x-9)
opening the parenthesis we have:
7x³+0x²-16x+8-4x³+6x²-8x+9
putting like terms together we get:
(7x³-4x³)+(-16x-8x)+(8+9)+(0x²+6x²)
=3x³+6x²-24x+17
the answer is
=3x³+6x²-24x+17
Answer:

Step-by-step explanation:
we are given equation as

Firstly, we will move all terms on left side
Subtract both sides by 20


Add both sides by 7x



now, we can compare it with quadratic equation

and we get

What kind of Question is that. That is some real math right there.
