Question

SOlve using the quadratic formula

4x²+7x+1=0

Answer 1

Given an equation in the form:
\[ax^2 + bx + c = 0\]
The quadratic formula is:
\[x = \frac{ -b ± \sqrt{b²-4ac} }{ 2a }\]

Answer 2

we can find the discriminant d=\[b ^{2}-4ac\]
we get d =33
now as d>0 we have two real values of x
using the formula
+-x=\[-B \pm \sqrt{d}/2a\]
