What Is The Interval For B Such That The Equation Has At Least One Real Solution?
2x^2+bx+5=0 show all work
Answer:
2x^2+bx+5=0
Either
bx = 7x or (5x+2x)
bx = 11x (10x+1x)
If bx = 7x then
2x^2+7x+5=0
2x^2+5x+2x+5=0
x(2x+5)+1(2x+5)= 0
(x+1)(2x+5)=0
either
2x+5 = 0 or x+1 = 0
2x=-5 or x= -1
x= -5/2 or x= -1 >>>answer
If bx = 11x afterwards
2x^2+11x+5=0
2x^2+10x+x+5=0
2x(x+5)+1(x+5)= 0
(2x+1)(x+5)=0
either
2x+1 = 0 or x+5 = 0
2x= -1 or x=-5
x= -1/2 or x= -5 >>answer
