Answer:
- 2 + 5x² - 2x + 4
Step-by-step explanation:
A polynomial in standard form has the leading term( first term) of the term with the largest exponent.
Other terms then follow in descending powers.
Given
5x² - 2 + 4 - 2x
The term with the largest exponent is - 2 ← becomes first term
Thus the polynomial can be expressed as
- 2 + 5x² - 2x + 4 ← in standard form
Answer:
x = 2 y = 1
Step-by-step explanation:
Given the system of equation
Y+ 2x = 5 ...1
4y+ 5x=14 ,,,,2
From 1;
y =5 - 2x ....3
Substitute 3 into 2
4(5-2x) + 5x = 14
20 - 8x + 5x = 14
20 - 3x = 14
-3x = 14-20
-3x = -6
x = 6/3
x = 2
Since y = 5-2x
y = 5-2(2)
y = 5-4
y = 1
Hence the required solution is (2,1)
