Question

the area of a square is given by the expression 64k² - 112k + 49, then what will be its side?​

Answer 1

Answer:

side = 8x-7

Step-by-step explanation:

64k² - 112k + 49

Rewrite 64k² as (8x)² and 49 as 7²

(8x)²-2(8) (7) +7²

a²-2ab+b²= (a-b) ²

(8x)²-2(8) (7) +7² = (8x-7) ²

area of the square = side²
