Basically, expand
expand them seperately to reduce confusion
exponent first
(x-4)^2=(x-4)(x-4)=x²-4x-4x+16=x²-8x+16

(x+5)(3x-1)=3x²+15x-x-5=3x²+14x-5

3x²+14x-5-(x²-8x+16)
3x²+14x-5-x²+8x-16
3x²-x²+14x+8x-5-16
2x²+22x-21

answer is
2x²+22x-21

SUPER HARD QUESTION (I POSTED THE DIAGRAM) In the diagram of.....
Kisachek [45]

Answer:

A

Step-by-step explanation:

Since m∠JOK is 1/5th of the measure of the full circle (we know this because 72° is 1/5th of 360° and 360° is the measure of the whole circle), we know that the measure of minor arc JK will be 1/5th of the circumference of the circle. C = 2πr and we know that r = 5 so the circumference is 10π. 1/5th of that is 2π.
