Question 103417This question is from textbook
: I have these two quadratic equations that I have to solve.
and
I know how to factor and I'm aware of the zero product property...but I'm not sure that regular factoring is the right way to solve this problem. Can you help me out, please? This question is from textbook
You can put this solution on YOUR website! 5x^2 + x + 2 = 0
Use the quadratic formula to get:
x = [-1 +- sqrt(1-4*5*2)]/10
x = [-1 +- sqrt(-39)]/10
x = [-1 + isqrt(39)]/10 or x = [-1 - isqrt(39)]/10
----------------------------------
and
2x^2 + 6x + 12 = 0
x^2+3x+6=0
x = [-3 +- sqrt(9-4*1*6)]/2
x = [-3 + isqrt(15)]/2 or x = [-3 -isqrt(15)]/2
--------------------------------------
