To solve the equation t² - t = 12 by factoring, you would use t(t - 1) = 12 t(t - 1) - 12 = 0 (t - 4)(t + 3) = 0

t^2-t=12

t^2-t-12=0

(t-4)(t+3)=0

t=4, -t^2-t=12

t^2-t-12=0

(t-4)(t+3)=0

t=4, -t^2-t=12

t^2-t-12=0

(t-4)(t+3)=0

t=4, -t^2-t=12

t^2-t-12=0

(t-4)(t+3)=0

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
