Question

y²+3y-18=0 by factorsation method

Answer 1

Hii friend,


Y²+3Y-18 = 0

=> Y²+6Y-3Y-18

=> Y(Y+6) -3(Y+6) = 0

=> (Y+6)(Y-3) = 0

=> (Y+6) = 0 OR (Y-3) = 0

=> Y = -6 OR Y = 3.



HOPE IT WILL HELP YOU...... :-)

Answer 2

$y {}^{2} + 3y - 18 = 0$

$y {}^{2} + 6y - 3y - 18 = 0$

$y(y + 6) - 3(y + 6) = 0$

$(y - 3)(y + 6) = 0$

$y = 3 \: \: and \: \: y = - 6$


Thanks
