Question

How many solutions will this quadratic equation x^2+8x+16 has?

Answer 1

Answer:

one solution

Step-by-step explanation:

to find out how many solutions a quadratic equation (with the equation ax²+bx+c) will have, we need to find the discriminant, which is b²-4ac

first, we can label the coefficients as a, b, and c

a=1 (1 is in front of x²)

b=8

c=16

now substitute into the formula

D=(8)²-4(1*16)

D=64-64

D=0

the discriminant is 0

when the discriminant is 0, that means the quadratic equation only has one solution.

Hope this helps!
