| Question | Answer |
| Expand and Simplify: (m+7)(m+3) | m²+7m+3m+21 =m²+10m+21 |
| Factorise the following: 1)6+9x 2)y²-16 3)2p²-p-10 | 1)6+9x =3(2+3x) 2)y²-16 =(y+4)(y-4) 3)2p²-p-10 =(2p-5)(p+2) |
| Solve by factorising the equation: 8x²-30x-27=0 | (2x-9)(4x+3) |
| Rearrange: a(q-c)=d to make q the subject | q-c=d/a q=d/a+c |
| P=n²+a/n+a Rearrange the formula to make a the subject | nP=aP=n²+a aP-a=n²-nP a(P-1)=n²-nP a=n²-nP/P-1 |
