Question

x^(2)-1369 are (a) (x-47)(x+47) (b) (x-47)(x-37) (c) (x-37)(x+37) (d) (x-37)^(2)​

Answer 1

Answer:

Step-by-step explanation:

a^2-b^2= (a+b)(a-b)

x^2-1369= (x+37)(x-37)

ans is option c

Answer 2

Answer:

(2x+1)^2+(x+1)^2=6x+47

then, use formula (a+b)^2

so,4x^2+4x+1+x^2+2x+1=6x+47

further x^2=45\5

therefore,x=√9

then,x=3
