Answer with explanation:
a)
[tex]\dfrac{16x^2+48x}{8x}[/tex]
Since, both the terms in the numerator have a common factor as: 8x.
Hence, we take out common 8x from the numerator term and hence it could be written as:
[tex]\dfrac{8x(2x+6)}{8x}[/tex]
i.e.
[tex]=2x+6[/tex]
b)
[tex]\dfrac{56x^2-14x}{7x}[/tex]
Since, both the terms in the numerator have a common factor as: 14x.
Hence, we take out common 14x from the numerator term and hence it could be written as:
[tex]=\dfrac{14x(4x-1)}{7x}\\\\=2(4x-1)\\\\=8x-2[/tex]
c)
[tex]\dfrac{(18x^2+15x)}{3x}[/tex]
Since, both the terms in the numerator have a common factor as: 3x.
Hence, we take out common 3x from the numerator term and hence it could be written as:
[tex]=\dfrac{3x(6x+5)}{3x}\\\\=6x+5[/tex]
d)
[tex]\dfrac{20x^2-32x}{4x}[/tex]
Since, both the terms in the numerator have a common factor as: 4x.
Hence, we take out common 4x from the numerator term and hence it could be written as:
[tex]=\dfrac{4x(5x-8)}{4x}\\\\=5x-8[/tex]
