Answer:
25x^2 -1
Step-by-step explanation:
If you multiply parentheses:
(5x*5x) + (5x*-1) + (1*5x) + (1*-1)
25x^2 - 5x + 5x -1
25x^2 -1
A simpler way is to memorize this formula
(Square1 - square2)= (sqrt of square1- sqrt of square2)*(sqrt of square1 + sqrt of sqaure2)
Okay I dislike improper fractions but the way to do this
see how many times the bottom number (denominator) goes into the top number (numerator)
4 can go into 15 3 times so 3 is your whole number
now you have 15-12=3 and that last three will be your next numerator
so your answer will be
3 3/4
