Question

What is the value of y^2-x^2y
2
−x
2
y, squared, minus, x, squared when y=6y=6y, equals, 6 and x=5x=5

Answer 1

Answer: 11

Explanation:

Let's start by substituting y=\greenD6y=6y, equals, start color #1fab54, 6, end color #1fab54 and x=\blueD5x=5x, equals, start color #11accd, 5, end color #11accd into the expression.

y^2-x^2y

y, squared, minus, x, squared

\greenD6^2 -\blueD5^26

−5

2

start color #1fab54, 6, end color #1fab54, squared, minus, start color #11accd, 5, end color #11accd, squared

Hint #22 / 3

Now we can simplify:

\begin{aligned}\greenD6^2 &-\blueD5^2\\ =\greenD{36}&-\blueD{25} \end{aligned}

6

Hint #33 / 3

\greenD{36}-\blueD{25} = 1136−25= 11

that is math:)
