MYP3 Algebra KWL pre-knowledge quiz

Simplify: $-3bc\times2ab$  

•  $5abc$  

•  $6ab^2c$  

•  $-6ab^2c$  

•  $-6\left(abc\right)^2$  

Simplify $\frac{2ab^2}{8ab}$  

•  $\frac{b}{4}$  

•  $\frac{1}{4b}$  

•  $\frac{a}{4b}$  

•  $\frac{b}{4a}$  

•  $\frac{1}{4}b$  

Simplifying $4ab-7a^2b+2b-ba+2a^2b$  leads to ______________

(Use ^ to write powers:  $x^2$  = x^2)

Expand, simplifying if possible: $-3\left(x+3\right)$  

• –      3       (x           +          3       )

•  $-3x\ +\ 9$  

•  $-3x\ -9$  

•  $-3x\ -\ 3$  

Expand, simplifying when possible: $2x\left(5-x\right)$  leads to ___________

(Use ^ to denote a power:  $x^2$  = x^2)

Simplify $9xy-4x\left(2x+y\right)$  

•  $9xy-6x+4xy$  

•  $5xy-6x^2$  

•  $5xy+8x^2$  

•  $5xy-8x^2$  

Solve the equation: $2x+3=9$  

Solve $\frac{5-6x}{4}=2$  

Solve: $8x-3=5x+9$  

Solve $5\left(3x+2\right)=2\left(9x-4\right)$
