Term 2 End Jeopardy Algebra

Collecting Like Terms

100

TRUE OR FALSE

Like terms AND unlike terms can be added or subtracted

FALSE - only like terms can be added or subtracted

200

Which three of the following are like terms:

11y, 4x, 6xy, -9x, 10x², 15xyz, 3xy², 0.5x

4x, -9x, 0.5x

300

Simplify by collecting like terms

-9p - 10p +13p - 14p

-20x

400

Simplify by collecting the like terms:

16xy - 11yx +13x - 2x

= 5xy + 11x

500

Simplify by expanding and then collecting the like terms:

5(h + 2p) - 5p + h

= 5h +10p -5p +h

=6h +5p

Multiplying Terms

100

TRUE OR FALSE: you can only multiply like terms?

FALSE - you can multiply any terms

200

Simplify: 3m x 5

15m

300

Simplify:

8f x 2g x g

= 16fg²

400

Simplify:

4kp x 5p² x ek

10ek²p³

500

Simplify

4a x 2bc x 5 x a x b³ x -10c

= -400a²b⁴c²

Dividing Terms

100

TRUE OR FALSE - you can't divide like terms

FALSE - you can divide any terms even if they are not alike.

200

(9b)/(3b)

= 3 

300

(16xy)/(8x)

= 2y

400

(20*2w^2y * xyz)/(4w)

=10wxyz

500

(10d^3ef^3 * -9de^2)/(2d^3e^2)

-45def^3

Expanding Brackets

100

TRUE OR FALSE

a(b+c) = ac + ab

TRUE - it's just in a different order!!!

200

TRUE OR FALSE:

5m (4m + 3) = 20m+15

FALSE:

5m(4m+3) = 20m²+15m

300

6(p-6) = ???

6p - 36

400

-jp(3j+10p)

= ???

-3j^2p-10jp^2

500

2t(5t^2 - 3)+6t(1-t^2)

=10t^3 - 6t +6t - 6t^3

=4t^3

Substituting Values

100

if a = 4, then 3a = ?

3a = 3x4 = 12

200

if b= -5 then, 

-b = ??

positive 5 

[-(-5) = +5]

300

if g = 6 and h = 9, then

2g + 4h -2 = ???

12 + 36 - 2 = 46

400

if a = 5, and b = -2, and c =1, then:

-3a + 2b² - 4c = ???

-3x5  + 2(-2)² - 4x1

= -15 + 2x4 - 4

= -15 + 8 - 4

= -7 -4

= -11

500

If x=2 and y= -1, solve:

(2+5xy)/(3x^2)

= (2+5*2*(-1))/(3*2^2)

=-8/12

=-2/3
