Find the xintercepts fxx28x10Solutionfxx28x10 for x intercep

Find the x-intercepts: f(x)=x^2+8x+10

f(x)=x²+8x+10

for x intercepts f(x)=0

=>x²+8x+10=0

by quadratic formula,ax^2 +bx +c =0 ==>x=[-b+(b²-4ac)]/(2a),x=[-b-(b²-4ac)]/(2a)

x=[-8+(8²-4*1*10)]/(2*1),x=[-8-(8²-4*1*10)]/(2*1)

x=[-8+24]/2,x=[-8-24]/2

x=-4+6,x=-4-6

x intercepts are (-4-6,0),(-4+6,0)
