Answer:
(x+5)²-10x²
Step-by-step explanation:
USing the completing square method
x² +25
= (x)² +2(x)(5) +(5)² -10x²
=(x+5)²-10x²
<h3><u>The first number, x, is equal to 955.</u></h3><h3><u>The second number, y, is equal to 191.</u></h3>
x = 5y
x - y = 764
Because we have a value for x, we can plug it into the second equation to solve for y.
5y - y = 764
Combine like terms.
4y = 764
Divide both sides by 4.
y = 191
Because we have a value for y, we can solve for x.
x = 5(191)
x = 955
Answer:
