Question

Solve 11+5+3x2+8x1 =

Answer 1

$Solutions$

$=11+5+3x^2+8x^1 =11+5+3x^2+8x$

Combine Like Terms:

$=11+5+3x^2+8x =(3x^2)+(8x)+(11+5) =3x^2+8x+16$

Simplify$=3x^2+8x+16$

Answer 2

Hai Hun =^.^=

You see, you use PEMDAS to solve this particular equation.

PEMDAS is Parentheses, exponents, multiply/divide, addition/subtraction. (Or for Please Excuse My Dear Aunt Sally)

When using PEMDAS you solve everything in the equation in that order, so your equation was 11+5x2+8x1=

So you go through each step of PEMDAS.

Parentheses? Nope. *check that off*

Exponents? Nope *check that off*

Multiply/Divide? Yes! (To clarify, multiply and divide are two separate thing combined for one step. So you just solve whatever comes first)

Addition/Subtraction? Yes!

If it's easier, it's okay to separate what you're working on at hand from the rest of the equation momentarily.

11+ (5x2) + (8x1) =

11 + 10 + 8 =

Now we're at the final stage of PEMDAS. You just add or subtract! (depending on whether the number is negative or positive)

11 + 10 + 8 =

(11+10) +8=

21 + 8 = 29

That's all there is to it! With practice it gets a LOT easier. I hope this helped!
