Factorise the quadratic equation x^2 + 14 + 48 hence solve the quadratic equation x^2 + 14 + 48 = 0

Technically speaking, histograms are another version of bar charts, if you need to work one out then skim through google hope-o that -o!

The third and fourth box.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
