What is an expression?An expression is a combination of numbers, variables, and functions such as addition, subtraction, multiplication or division, etc.
We have,
2a² - ( 4b + c ) ______(1)
a = -3, b = -2 and c = 1
Substitute a, b, and c in (1)
= 2 x (-3)² - ( 4(-2) + 1 )
= 2 x 9 - ( -8 + 1 )
= 18 - ( -7 )
= 18 + 7
= 25
Thus the value of the expression 2a² - ( 4b + c ) is 25.

The polynomial p(x)=3x^3-19x-30 has a known factor of (x+2). Rewrite p(x) as a product of linear factors. p(x) =
A linear combination of elements. p(x) =(x-10)(x-19)(x+2)
How do linear factors work?The first-degree equations that make up a polynomial's linear factors serve as the foundation for higher-order and more complicated polynomials.
The formula for a linear factor is ax + b, and it cannot be factored further.
A polynomial is what?Sums of terms with the form k xₙ, where k is any number and n is a positive integer, make up polynomials.
According to the provided equation, for instance,
3x+2x-5 is a polynomial;
p(x)=3x3-19x-30
x(x-19)-10 =0
=(x-10)(x-19)(x+2).

Nigel wants to average 85% on his four tests. He got 77%, 89%, 78% on his first three tests. What does he need to get on his last test to average 85%?
Answer:
Step-by-step explanation:
Let x be the value of the test score needed to get 85
Equation
(77 + 89 + 78 + x)/4 = 85 Combine the left side to like terms
(244 + x)/4 = 85 Multiply by 4
244 + x = 85 * 4
244 + x = 340 Subtract 244
x = 340 - 244
x = 96
He needs to get 96 to average out to 85
