Q17 of 134 Page 4

Determine whether the given values ofĂÂ x are solutions of the givenequation or not:
(x + 4)(x - 5) = 0; x = -4, x = 5.

Put x = -4
(x + 4)(x - 5)

= (-4 + 4)(-4 -5)

= 0(-9 )

= 0
Put x = 5
(x + 4)(x - 5)

= (5 + 4)(5 - 5)

= 9(0)

= 0
Therefore the given value of x is a solution of the given equation.
