Simplify a + b - c a is equal to 4 x to the power of 3 + 3 x minus 19 ...
Given Equations:
a = 4x^3 + 3x - 19
b = x^3 + 8x^2 - 7x + 13
c = -x^3 + 6x + 20
Solution:
Step 1: Simplify a + b - c
a + b - c = (4x^3 + 3x - 19) + (x^3 + 8x^2 - 7x + 13) - (-x^3 + 6x + 20)
= 4x^3 + 3x - 19 + x^3 + 8x^2 - 7x + 13 + x^3 - 6x - 20
= 4x^3 + x^3 + x^3 + 8x^2 + 3x - 7x - 6x - 19 + 13 - 20
= 6x^3 + 8x^2 - 10x - 26
Therefore, a + b - c = 6x^3 + 8x^2 - 10x - 26
Final Answer:
a + b - c = 6x^3 + 8x^2 - 10x - 26
In this way, the value of the expression a + b - c has been simplified and calculated.
a = 4x^3 + 3x - 19
b = x^3 + 8x^2 - 7x + 13
c = -x^3 + 6x + 20
Solution:
Step 1: Simplify a + b - c
a + b - c = (4x^3 + 3x - 19) + (x^3 + 8x^2 - 7x + 13) - (-x^3 + 6x + 20)
= 4x^3 + 3x - 19 + x^3 + 8x^2 - 7x + 13 + x^3 - 6x - 20
= 4x^3 + x^3 + x^3 + 8x^2 + 3x - 7x - 6x - 19 + 13 - 20
= 6x^3 + 8x^2 - 10x - 26
Therefore, a + b - c = 6x^3 + 8x^2 - 10x - 26
Final Answer:
a + b - c = 6x^3 + 8x^2 - 10x - 26
In this way, the value of the expression a + b - c has been simplified and calculated.
