Question

Add the following algebraic expressions vertically
c) (3x4 – 2x2 + x – 17) + (14x4 – 12x3 + 2x4 + 7x3 + 2x2 - 4x - 2)​

Answer 1

Answer:

19x^4. --5x^3 --3x --19

Step-by-step explanation:

arrenge them in a table and then add

3x^4 -- 0x^3 -- 2x^2 + x -- 17

+. 14x^4 -- 12x^3 + 0x^2 + 0x + 0

+ 2x^4 +. 7x^3. + 2x^2 - 4x. - 2

by adding we get

19x^4 -- 5x^3 +. 0x^2. -- 3x. -- 19

Answer 2

Answer:

Question :-

c) (3 × 4 - 2 × 2 + x - 17) + (14 × 4 - 12 × 3 + 2 × 4 + 7 × 3 + 2 × 2 - 4x - 2)

Answer :-

➠ (3 × 4 - 2 × 2 + x - 17) + (14 ×4 - 12 × 3 + 2 ×4 + 7 × 3 + 2 × 2 - 4x - 2) = 0

➻(12 - 4 + x - 17) + (56 - 36 + 8 + 21 + 4 - 4x - 2) = 0

➻ (8 - 17 + x) + (20 + 8 + 25 - 2 - 4x) = 0

➻ (-9 + x) + (28 + 25 - 2 - 4x) = 0

➻(-9 + x) + (53 - 2 - 4x) = 0

➻ -9 + x + 51 - 4x = 0

➻ - 4x + x - 9 + 51 = 0

➻ - 3x + 42 = 0

➻ - 3x = - 42

➻ x = $\dfrac{-42}{-3}$

➻ x = 14
