Please help with quadratic equations ASAP please!!

solve for 'x'

12. -5 = 4x^2 + 2
11. -10 = -x^2 + 2x - 6
10. 0 = x^2 - x - 30

PLEASE SHOW WORK ASAP !!!!!EACH QUESTION WOULD HELP PLEASE

12. x^2= -7/4, x= positive and negative i radical seven all divided by 2. There isn't much work for that.
11. 0= x^2-2x-4, use the quadratic formula. x=1-radical 5 and x= 1+radical 5
10. factor it. 0=(x-6)(x+5). x=6 and x=-5
