outer heart help me lmfao <@&791435371564892232>

the formula u wrote for the area of the sector is right

#

but to work out A, you need to substitute in 3x-1 and 5x-1

#

lemme try write it out for u

if ur confused anywhere lmk

#

i did all the expanding and factorising in my head so i may have made a mistake

outer heart Apr 29, 2023, 4:59 PM

#

How did u times 1/8 to both sides

#

😭

stone flint Apr 29, 2023, 4:59 PM

#

to get rid of 1/8 i multplied the other side by 8

outer heart Apr 29, 2023, 5:00 PM

#

Was it also common to the other bracket

#

The 9x^2 - 6x -1

stone flint Apr 29, 2023, 5:01 PM

#

yeah the 1/8 was for both quadratics on the lhs
