Question

If a²-b²=275,a+b=25,then value of a-b= .........
​

Answer 1

Answer:

(a-b)=11

Step-by-step explanation:

${a}^{2} - {b}^{2} = 275\\ = (a + b)(a - b) = 275 \\ = 25 \times (a - b) = 275 \\ = (a - b) = \frac{275}{25 } \\ = (a - b) = 11$

Answer 2

formula to be used:-

$\huge \fbox \ blue{a²-b²=(a+b)(a-b)}$

solution

(a+b)(a-b)=275

25(a-b)=275

a-b = 11
