Question

Solve x^2+7x-2=0

what are the solutions?

find the x-intercepts of f(x)=x^2+7x-2



find and label the vertex and the line of symmetry.
f(x)=(x+3)^2
the vertex is?
the equation of the line of symmetry is x=



Give and approximate solutions to three decimal places.
x^2-5x+3=0
the exact solitions are x=
the approximate solutions to 3 decimal places are x=

Answer 1

f(x)=x^2+7x-2 x intercepts are approx 0.275 and -7.275

(x+3)^2= x^2+6x+9 vertex is (-3,0)
the equation of the line of symmetry is x=-3

x^2-5x+3=0
the approximate solutions to 3 decimal places
are x = 4.303 0.697

THAT'S MORE THAN ONE QUESTION!
