need help.  solve using quadratic formula, aproximate solution to nearest tenth.                                    5x²6+5x answ
Alona [7]
<u>5x² + 5x + nothing</u>
Ax² + Bx + C

A = 5
B = 5
C = 0

Quadratic formula:

x = (1/2A) times [ -B plus and minus √(B²-4AC) ]

B² - 4AC = 25 - 4(5)(0) = 25
 
-B plus and minus √25 = -5 plus and minus 5 = -10 and zero.

(1/2A) times (-10 and zero) = (1/10) times (-10 and zero) = -1 and zero

x = 1
and
x = 0
