If x + y = 10 and x - y = 4, find the value of x² - y²
2 answers:
Answer:
x²-y² = 40
Step-by-step explanation:
Factorising x²-y²:
x²-y² = (x+y)(x-y)
This is due to the property that states:
a²+b² = (a+b)(a-b)
Substituting the given values into the above equation:
x²-y² = (10)(4)
= 40
Hence, x²-y² = 40

Answer:
x² - y²=40 or 7²-3²=40
Step-by-step explanation:
if x=7 that would make y=3
7+3=10 and 7-3=4
7x7=49
3x3=9
49-9=40
