Answer:
-1
Step-by-step explanation:
-5-15+4+15
=-20+19
=-1
Discriminant D is given by:
D=b²-4ac
Implication of discriminant is as follows:
D<0 two zeros that are complex conjugate
D=0 one real zero of multiplicity 2
D>0 two distinct real zers
D= (+ve perfet square) two distinct rational zeros
From:
12x^2+10x+5=0
plugging in the equation we get:
10²-4×12×5
=100-240
=-140
thus
D<0
Answer is:

54=.9x Solve for x. x=54/.9=60
12 + 26 + 125 = 163
163 + 0.056(163) = 163 + 9.13 = 172.13
