Question

74×86=(...-...)(...+...)​

Answer 1

Ответ:

74×86=(100-26)(36+50)

Answer 2

To find the product of 74 and 86 in the form of (a - b)(c + d), we can use the FOIL method of multiplying binomials.

Let's assume a = 80, b = 6, c = 80, and d = 6.

Then, we have:

(80 - 6)(80 + 6)

Now let's simplify this expression:

(74)(86) = (80 - 6)(80 + 6)

Expanding the expression using the FOIL method:

(80 - 6)(80 + 6) = (80 * 80) + (80 * 6) - (6 * 80) - (6 * 6)

Simplifying further:

(80 * 80) + (80 * 6) - (6 * 80) - (6 * 6) = 6400 + 480 - 480 - 36

Finally, evaluating the expression:

6400 + 480 - 480 - 36 = 6364

Therefore, 74 multiplied by 86 is equal to (80 - 6)(80 + 6), which simplifies to (6364).
