unklerhaukus · Answer

say one of your options was      (3x  +  4)(2x  -  5)

you can expand the brackets by multiplying

$$(3x  +  4)(2x  -  5)=6x^2-15x+8x-20$$

unklerhaukus · Answer

what do you get when you expand the brackets of 

 (2x  +  1)(2x  -  6)=

unklerhaukus · Answer

$$(2x  +  1)(2x  -  6)=(2x\times2x)+(2x\times-6)+(1\times2x)+(1\times-6)$$
