I need help with this

Step-by-step explanation:

a,) 36

b) 36

c) 36-4(-1)(-9)= 36-36= 0

d) number of solution is one

Step-by-step explanation:

the given equation is in the form of quadratic formula i.e.ax^2+bx+c=0.

So ,here a=-1 ,b=-6 and c=-9

b^2=(-6)^2

=36

4ac=4*(-1)*(-9)

=4*9

=36

b^2-4ac=36-36

=0

number of solutions =1

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
