If you dont follow the right steps in the right order or properly, you won't end up with the right answer:
For example 3 x 5 + 7
If you do multiplication then add you get 22 which is correct.... but!!
If you add then do multiplication you get 36 which isn't right
Remember always follow PEMDAS
P-Parenthesis
E-Exponents
M or D- Multiplication or division (go left to right)
A or S- Addition or Subtraction (go left to right)
Answer:
- 23/13
Step-by-step explanation:
1. Subtract 5/2 from both sides of the equation.
2. Simplify
7/5 = /10 − 23/10
3. Multiply all terms by the same value to eliminate fraction denominators.
7/5 = /10 − 23/10 2 ⋅ 5 ⋅ 7/5 = 2 ⋅ 5( /10 − 23/10)
4. Simplify
14 = − 23
5. Subtract from both sides of the equation.
14 = − 23 14 − = − 23 −
6. Simplify
13 = − 23
7. Divide both sides of the equation by the same term.
13<em>x </em>= −23 13x/13 = -23/13
8. Simplify
= −23/13
10g^3 + 12g^2 - 15g - 18 = 2g^2(5g + 6) - 3(5g + 6) = (2g^2 - 3)(5g + 6)
