Question

explain how you would use the quadratic formula to solve x2 + 7x = –3.

Answer 1

x²+7x = -3
x²+7x+3 = 0
a = 1, b=7, c=3

x = [-b ± sqrt(b²-4ac)] / 2a
= [-7 ± sqrt( (-7)² - 4(1)(3) )] / 2(1)
= (-7 ± sqrt( 37 )) / 2

Answer 2

im not sure if thats right.. but thats my answer..

Answer 3

lol thank you

Answer 4

correction ,, its sqrt(7^2-4(1)(3)
