Hi, I'm currently working on Exam Q2 and I was wondering if there was a mistake at 7:31 because x^2 - 9x + 20 factorises to x=-5 or x=-4 ?? Is there something I'm missing, or is this the case because y=ln x is only defined for x>0, in which case I'm a little lost!
sure sir to bother you but for the final question surely B would = 1/4 because you would have to use the power rule to make the symbols the same. Anyways thank you dont know why i havent left a comment thanking you considering you have single handedly carried me throughout alevels being the only maths resource i use
Clarification - for exam style question 4, the - in front of ln4 should be taken to the power using power rule for logs, giving b=4^-1=1/4.

The brackets would give (x-5)(x-4)=0, either bracket must equal zero, therefore x-4=0, so x=4, or x-5=0, so x=5
Yeah you’re 100% right thanks, my brain had gone to mush at that point haha I was cramming for a test
I LOVE U!!!!!
u saved me bro

@@ris4314 not terrible but not amazing got the badge question and integration by substitution question wrong
@@HamzaElsharkawy-rb2ncI think majority of the people collectively got this question wrong. My teacher said they were the two hardest Qs on the paper
thank u so much

how is lne^x equal to x if lne = 1 and 1^x = 1 so wouldnt lne^x be 1
do you recommend anyone for A level OCR physics with the same energy as you.
