Hey guys, I am really confused with this work, I missed some
time from college as I was ill and missed the work. Can anyone
help me? Question 1 says, use appropriate methods to completely
factorise the following expression by extraction and grouping of
common factors. (A) 12a2b + 15ab2 (B) 10ab - 8ax + 15b - 12x
Question 2 says, solve a quadratic equation by factorising and
one by the formula method. a mojor leak is discovered on the
surface of oil storage tank in the workshop. the supervisor
decides that the best solution to this is to weld a
reinforcement sheet of metal on the leaking area. after taking
measurements, the following conditions are decided. - the are of
rectangular sheet of metal should be 24000mm2 - the length of
the sheet should be 10mm greater than the width Calculate the
dimensions of the reinforcement sheet. What would be the
dimensions if the area of the sheet was reduced wo 21987mm2?
Could someone please explain how to to this for me? Thank you!
