What is the simplified form of the quantity 4 x squared minus 25 over the quantity 4x minus 5?
Solution:
We will use the concept of algebraic expression in order to find the simplified form.
Let us first write 4 x squared minus 25 in an algebraic form which will be equal to (4x)2 - 25
Now, (4x)2 - 25 = 16x2 - 25
Now 4 x squared minus 25 over the quantity 4x minus 5 will be equal to (16x2 - 25) / (4x - 5)
We will use algebraic identity a2 - b2 = (a + b)(a - b)
Hence, 16x2 - 25 = (4x + 5) (4x - 5)
Therefore, (16x2 - 25) / (4x - 5) = (4x + 5) (4x - 5) / (4x - 5)
Hence, the simplified form of the quantity 4 x squared minus 25 over the quantity 4x minus 5 is 4x + 5.
What is the simplified form of the quantity 4 x squared minus 25 over the quantity 4x minus 5?
Summary:
The simplified form of the quantity 4 x squared minus 25 over the quantity 4x minus 5 is 4x + 5.
