Question

What is completely factored form or this expression?

y^2-12y+32

a.(y+4)(y+8)
b.(y-4)(y-8)
c.(y+18)(y+2)
d.(y-18)(y-2)

Answer 1

Answer :)

• 
  `\sf{y^(2)-12y+32 }`

• 
  `\sf{y^(2)-(8+4)y+32 }`

• 
  `\sf{y^(2)-8y-4y+32 }`

• 
  `\sf{ y(y-8)-4(y-8) }`

• 
  `\sf{(y-8)(y-4) }`

• 
  `\sf{(y-4)(y-8) }`

`\\\\\\`

Therefore

• 
  `\sf{option~ B~ is ~correct }`

`\sf{ }`
`\sf{ }`
`\sf{ }`

Answer 2

(y-4) (y-8)

Explanation:

y^2-12y+32

What two numbers multiply to 32 and add to -12

-8*-4 = 32

-8+-4 = -12

(y-4) (y-8)
