Answer:
C) (x-6)^2
Step-by-step explanation:
x2 - 12x+36
What two numbers multiply to 36 and add to -12
-6*-6 = 36
-6+-6 = -12
(x-6) (x-6)
(x-6)^2
Answer:
11 or -16
Step-by-step explanation:
The square of a number increased by 5 times the number is equal to 176.
Let the number be x
Then, x²+5x=176
x²+5x-176=0
We use splitting the middle term method
x²+16x-11x-176=0
x(x+16)-11(x+16)=0
(x-11)(x+16)=0
i.e. either x-11=0 or x+16=0
i.e. either x=11 or x=-16
Hence, the number is either 11 or -16
The equation above has no real solution because it has no real number 0 is not a number that can take place of a real solution.
Hope This helped;D
