Question 2 please fas

Len [333]

Answer:

a = 3, b = 2

Step-by-step explanation:

It is given that both the polynomials are equal.

Therefore, h(x) = k(x)

${x}^{3} + (a + b) {x}^{2} - 4x + 2 \\ = {x}^{3} + 5 {x}^{2} - (2a - b)x + 2 \\ \\ equating \: like \: terms \: on \: both \: sides \\ (a + b) {x}^{2} = 5 {x}^{2} \\ \implies \: a + b = 5.....(1) \\ \\ - (2a - b)x = - 4x \\ 2a - b = 4....(2) \\ \\ adding \: equations \: (1) \: and \: (2) \\ \\ 3a = 9 \\ \implies \: a = \frac{9}{3} \\ \huge \red{ \boxed{\implies \: a = 3}} \\ \\ substituting \: a = 3 \: in \: equation \: (1) \\ 3 + b = 5 \\ \implies \: b = 5 - 3 \\ \huge \purple{ \boxed{ \implies b = 2}}$

Which number is the farthest from - 2 on the number line?<br><br>A. 6<br>B. 0<br>C. -1<br>D. -9

Leya [2.2K]

Answer: A. 6

Step-by-step explanation: if you go from -2 to 6 you go 8 spaces. You go from -2 to 0 which is 2 spaces, and they 6 more spaces to get to 6. If you went to -9 you are going 7 spaces. and to 0 you go 2 spaces, and -1 you go one space. So, the furthest is positive 6.

Hope this helps ^_^
