Question 350991: Chapter 10 10.3
64. Find all real solution to each equation. Thank you much.
x^2 + x + sqrt (x^2+x)-2=0
70. Find all real and imaginary solution to each equation.
b^2 + 13b^2 + 36=0
48. Find b2 4ac and the number of real solutions to each: -3x^2+7x=0
Answer by edjones(8007) (Show Source): You can put this solution on YOUR website!
-3x^2+7x=0
a=-3, b=7, c=0
b^2-4ac
=49-4*-3*0
=49
.
There are 2 real answers because 49 is positive and greater than zero.
