Question

x²-3x-504=0

iske age ka 1 step koi kar do ?​

Answer 1

${x}^{2} - 24x + 21x - 504 = 0 \\ \\ x(x - 24) + 21(x - 24) = 0 \\ \\ (x - 24)(x + 21) = 0 \\ \\ x = 24 \\ \\ x = - 21$

hope it helps.

Answer 2

Hello friends!!

Here is your answer :

Method 1:

PRIME FACTORISATION

x² - 3x - 504 = 0

=> x² - ( 24 - 21 )x - 504 = 0

=> x² - 24x + 21x - (21 × 24) = 0

=> x ( x - 24 ) + 21 ( x - 24 ) = 0

=> ( x - 24 )( x + 21 ) = 0

=> x = 24. or x = -21

Method 2:

Quadratic formula
