Answer:
Missing Coefficient is -8
Step-by-step explanation:
We are given, _y² - [ -5y - y( -7y -9) ] - [ -y(15y + 4) ] = 0
We have to find missing value.
let missing value be a
ay² - [ -5y - y( -7y - 9) ] - [ -y(15y + 4) ] = 0
ay² - [ -5y + 7y² + 9y ] - [ -15y² - 4y ] = 0
ay² - [ 7y² + 4y ] + 15y² + 4y = 0
ay² - 7y² - 4y + 15y² + 4y = 0
ay² - 7y² + 15y² + 4y - 4y = 0
( a - 7 + 15 )y² = 0
RHS can be written as
( a - 7 + 15 )y² = 0.y²
Now comparing coefficient of both sides we get,
a - 7 + 15 = 0
a + 8 = 0
a = -8
Therefore, Missing Coefficient is -8
Answer: 3p^3 (p+2)(p-2)
Answer: and
Step-by-step explanation:
Alright, lets get started.
The given equation is :
Adding 8 in both sides, it will become
To make it perfect square, we need to add 25 and subtract 25
Adding 17 in both sides
taking square root
So,
and .. Answer
Hope it will help :)
Answer:
Step-by-step explanation:
X² + 10x = -8
add to both side the square of half the coefficient of X which is 5²
X² + 10x + (10/2)² = -8 + (10/2)²
X² + 5² = -8 + 5²
( X + 5 )² = -8 + 25
(X + 5)² = 17
X + 5 = +- √17
Therefore, X = -5 +- √17.
X = -5 + √17 , -5 - √17.
