Question

Which function is equivalent to

k(x) = x² + 2x - 15

F K(x) = (x + 15)(x - 1)
G K(x) = (x + 1)(x - 15)
H K(x) = (x + 5)(x - 3)
J_k(x) = (x+3)(x - 5)

Answer 1

Option:-

• 
  `\rm{H) K( x ) = ( x + 5 ) ( x - 3 )}`

`\:`

Solution:-

• 
  `\rm{k ( x ) = x² + 2x - 15}`

[ multiplication of 5 × 3 = 15 ]

[ Subtraction of 5 - 3 = 2 ]

• 
  `\boxed{\rm{k ( x ) = ( x + 5 ) ( x - 3 )}}`
