Question

find the difference without subtraction
$35 { }^{2} - 34 {}^{2}$
​

Answer 1

Answer:

69

Step-by-step explanation:

35² - 34²

→ (a² - b²) = (a + b)(a - b)

→ (35² - 34²) = (35 - 34)(35 + 34)

→ (35² - 34²) = 1 × 69

→ (35² - 34²) = 69

Answer 2

Answer:

69

Step-by-step explanation:

35²- 34²

(a²- b²) = (a+b) (a-b)

(35²- 34²) = (35-34) (35+34)

(35²-34²) = 1×69

(35²-34²) = 69
