Step-by-step explanation:
(5√2-4√3)(5√2-4√3)=
(5√2-4√3)^2=(5√2)^2+(4√3)^2-2(5√2)(4√3)
=25*2+16*3-10√2*4√3
=50+48-10√2*4√3
=98-10√2*4√3 is the answer
257 is a whole number, interger, and a rational number.

Answer: 3(x^2 + 4)/(x - 5)(x + 4)
Step-by-step explanation:
To simplify, begin with 3x^2 + 12 by dividing by 3 first: 3(x^2 + 4)
x^2 - x - 20 can be simplified into (x - 5) (x + 4). To find these terms, you have to figure out what two numbers multiply together to equal -20 but also add to -1.
