+Christaingrey Well, the two integers of the factored expression must have the product -3, in order for the factored expression to be equivalent to the unfactored one. However, during factoring, either A or B will have the factor 7k factored out. So, a*b must be -3 _after_ (a or b, it doesnt matter) has been divided by 7k. In other words, (a*b)/7=-3 (devided by 7 because 7 will be factored out), or a*b=7*-3. I am sorry if this is wrong, or too chaotic to be comprehensible. I'm new to this too, and don't usually do maths in english, so I dunno the proper terms.
I'd just like to say that this really makes no sense how the sum of 7 and 3 =20 like honestly thsi subject makes me watn to throw myself down a flight of stairs
can someone answer this correctly ☺ (3x-4) (x+3) = x-8 i can't solve this bc all examples i see is something like "(3x-4)(x+3)=60" like that, thanks in advance!
Erin Stacy Amoin 1) Open up the paranthesis, you get: 3x^2 + 3x - 12 = x - 8 2) now get the x - 8 to the other side so we can equalize the equation now to zero, we get: 3x^2 + 2x - 4 = 0 3) now you can solve the rest with the technique he explains in the video Your questions is from two years ago but maybe this helps someone who sees this😂
You make it so simple! Great video!
Makes so much sense now
yeah no cap
Im sorry, but from where it leads that product of two numbers must be 7*-3?

I'm (35k^2 + 100k - 15)% sure that this guy just made up everything he said.
Umm... no, I strongly disagree

@@kayraozbakir9517 hope he found it even after three years, thanks for your help
