Calculus. Munerial Solutions ex-1= x²-gx-5=0 (x-1) (x-1)=0 X=1, X*1. ex2= x²-ex=0 F(x)=x²-x-2. F(x)=(x-2)(x+1 X-X-2-0 Xx+2 2 Methods - Graphical Alegraphic. Roots: Intersaction betwee Graph and Axis X2-1, x=2. Inter section between Ceraph. Grapichal In x+x-2:0 h(x) in x In x = 2-x g(x) = 2-x Alegraphic ex.3: show x²-1+9=0 has Poot thats (ren between 0.2 ando.3 F(x) = x²-1+1 2 X + 0.2, (0,2)²-02-19 = -0.960<0 FC0.3): (0.3)² = 0,757 70 +9 6.3
