How many solutions does this quadratic equation have ? y=x^2-8x-20
1 answer:
Answer: y=x+2 or x-10
Step-by-step explanation:
Y=x2-8x-20
Quadratic equation
Variables of -20 that will give -8 are
-10 &+2
Substitute into the equation
Y=x2-10x+2x-20
Y=x(x-10)+2(x-10)
Y=(x+2)(x-10)
The two equations are
Y=x+2 or
Y=x-10
