Answer:
Step-by-step explanation:
1/2y - 5/8y = 4/8y - 5/8y = -1/8y
3/4 - 7/8 = 6/8 - 7/8 = -1/8
-1/8y - 1/8 =
-y/8 - 1/8 =

Answer:
Step-by-step explanation:
1). x² - 10x + a²
By using the formula of (a - b)² = a² - 2ab + b²
x² - 2(5)x + a²
Therefore, for a perfect square of the expression a should be equal to 5.
Therefore, (x² - 10x + 25) will be the answer.
2). x² + 2ax + 36
= x² + 2(a)x + 6²
For a perfect square of the given expression value of a should be 6.
x² + 2(a)x + 6² = x² + 2(6)x + 6²
= (x + 6)²
Therefore, x² + 12x + 36 will be the answer.
3).
To make this expression a perfect square,
a² =
=
Therefore, the missing number will be .
