1.
(100 + d^2)(d + 10)(d - 10)
Use the rule of splitting perfect squares to get the factors.
2.
x^4y^8z^2(x^2z^6 - y)
The first term is the greatest common factor.
Answer:
x = 0 and y = 3
Step-by-step explanation:
Using elimination method, we can solve for x and y in the simultaneous equation
y = 2x + 3 .................................eqn 1
y = -3x + 3 .................................eqn 2
multiply equation 1 by 3 and equation 2 by 2, then we will have
(y = 2x + 3) × 3
(y = -3x + 3) × 2
3y = 6x + 9 ...............................eqn 3
2y = -6x + 6 ................................eqn 4
Add eqn 3 and 4 together and we will eliminate x and have
5y = 15
Divide both sides by 5, and we will have
y = 3
To solve for x, substitute 3 for y in eqn 1
y = 2x + 3
3 = 2x + 3
collect like terms
3 - 3 = 2x
0 = 2x
Therefore x = 0
X = -3 + (-1) + 0 + 2 + 3 + 5
x = -3 - 1 + 0 + 2 + 3 + 5
x = -4 + 0 + 2 + 3 + 5
x = -4 + 10
x = 10 - 4
x = 6
y = x + 2
y = (6) + 2
y = 8
