Use the quadratic formula to solve 5x^2+2x-3
Lisa [10]
Assuming it equals 0
for
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}

given
5x^2+2x-3=0
a=5
b=2
c=-3

x=\frac{-2+/- \sqrt{2^2-4(5)(-3)} }{2(5)}
x=\frac{-2+/- \sqrt{4+60} }{10}
x=\frac{-2+/- \sqrt{64} }{10}
x=\frac{-2+/- 8 }{10}
x=(-2+8)/10 or (-2-8)/10
x=6/10 or -10/10
x=3/5 or -1

A certain triangle has longest side three times it’s shortest side, the middle side is three less than the longest side. The per
Stells [14]

let the short side = x

Long side = 3x

Middle side = 3x -3


x + 3x + 3x -3 = 32

Simplify:

7x -3 = 32

Add 3 to both sides:

7x = 25

Divide both sides by 7:

X = 5


answer: shortest side = 5cm
