PLS HELP.... If 4x^2 + bx + 9 = 0, where b is the constant, has exactly one solution, what is a possible value of b ?
2 answers:
You can use the discriminant rule, which is : b^2 -4ac “exactly one solution” means that it is equal to zero so: b^2 -4(4)(9)=0 b^2 -4(36)=0 b^2 -144=0 b^2=144 square root both sides b=12 or -12 hope this helps !
Answer:
Since the equn is quadratic and has equal roots, it's delta k^2–4*4*9 =0 => k= (+ or -) 2*2*3 = (+ or -) 12
