Find the sum of the polynomials: (x2 + 4x + 5) + (3x – 3)

x^2+7x+2

Step-by-step explanation:

hi! you can only combine terms with the same power (exponent value).

if we stack this like a regular addition problem, it will be easier.

x^2  +  4x  +  5

           3x  -   3

4x+3x is 7x, and 5+ (-3) is 2. we keep the x^2 the same.

therefore, the answer is x^2+7x+2

hope this helps!

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
