Question

MEDAL given work two problems out pleaseee 1. x^2- 8x -7=0 2. x^2 -3x=40

Answer 1

when factorizing, you want to multiply your constant by the coefficient of x^2
in this case
1x-7=-7
you want to write out the factors of -7

1 -7
-7 1


next you want to find out which set of factors, when added together, gives the coefficient of x
in this case -8

in this case none of them add to give -8 so we use the quadratic formula

Answer 2

where a is the coefficient of x^2
b is the coefficient of x
c is the constant

Answer 3

i have the answer thats not it

Answer 4

4 plus or minus sqrt(23) should be the answer
