Hello
How would I go about this one please?
(8x – 1) × (8x – 1)
3x________(7x + 1)
Your formatting is difficult to read. I think you mean the following:
. . . . .$\displaystyle \frac{8x\, -\, 1}{3x}\, \times\, \frac{8x\, -\, 1}{7x\, +\, 1}$
To multiply fractions, you multiply their numerators and their denominators. For instance:
. . . . .$\displaystyle \frac{1}{3}\, \times\, \frac{4}{5}\, =\, \frac{1\, \times\, 4}{3\, \times\, 5}\, =\, \frac{4}{15}$
To simplify your fraction, multiply the 8x - 1 by the 8x - 1, and the 3x by the 7x + 1.
