work out the value of y when a = 6.5 and b = 3.5, given that y = (a+b)(a-b)
You asked:
Given the following equations: \[\begin{aligned}a &= 6.5\\ b &= 3.5\\ y &= \left(a + b\right) \cdot \left(a - b\right)\end{aligned}\] Evaluate \(y\).
MathBot Answer:
\[y = \left(a + b\right) \cdot \left(a - b\right) = \left(a - b\right) \left(a + b\right)\]
