5x 3y^3 2z
I know it is in standard form because there are no more like terms.
Part B: Polynomials are always closed under multiplication. Unlike with addition and subtraction, both the coefficients and exponents can change. The variables and coefficients will automatically fit in a polynomial. When there are exponents in a multiplication problem, they are added, so they will also fit in a polynomial.

Answer:
Explanation:
Using the PEMDAS rule:
P = parentheses
E = exponent
M = multiplication
D = division
A = Addition
S = subtraction
Step 1: 6 + 4 x 3 - 10/5
Step 2: 6 + 12 - 2
Step 3: 18 - 2
Step 4: 16
X² + 6x -12 = 0
x = <u>-(6) +/- √((6)² - 4(1)(-12))</u>
2(1)
x = <u>-6 +/- √(36 + 48)</u>
2
x = <u>-6 +/- √(84)
</u> 2<u>
</u>x = <u>-6 +/- 2√(21)
</u> 2<u>
</u>x = -3 <u>+</u> √(21)
x = -3 + √(21) x = -3 - √(21)
Answer: x=3
Step-by-step explanation:
7+5(x-2)=12
Open bracket
7+5x-10=12
Collect like terms
5x-3=12
5x=12+3
5x=15
X=15/5
X=3
