Answer:
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
Answer:
Answer:
A.) 2(-4) + 4(-4) + 3 = 7 -(-4) + 10
-8 -16 + 3 = 21
-24 + 3 = 21
-21 = 21
Answer= -1.
B.) 2(-2) + 4(-2) + 3= 7 -(-2) + 10
-4 -8 + 3 = 19
-12 + 3 = 19
-9 = 19
-2.1.
C.) 2(2) + 4(2) + 3 = 7 -(2) + 10
4 + 8 + 3 = 7 -2 + 10
15 = 15
1.
D.) 2(4) + 4(4) + 3 = 7 -(4) + 10
8 +16 + 3 = 7 -4 + 10
27 = 13
0.481.
