WebIf x is real, find the maximum and minimum values of x 2+2x+3x 2+14x+9. Medium Solution Verified by Toppr Let y= x 2+2x+3x 2+14x+9. ⇒y(x 2+2x+3)=x 2+14x+9 ⇒(y−1)x 2+2(y−7)x+3y−9=0 Since, x is real, so discriminant of above equation will be greater than or equal to 0.

There's a bunch of ways we could do it. We could factor it and just figure out the values of x that satisfy it and just count them. That will be the number of solutions. We could just apply the quadratic formula.

For instance, to measure distances when building a house it suffices to use a tape measure with an accuracy of about of an inch. However, to do mathematical analysis the rational numbers have some very serious shortcomings; here is a an example.
Web5 jul. 2024 · "If `x`is a positive real number and `x^2=2,`then `x^3=``sqrt(2)` (b) `2sqrt(2)` (c) `3sqrt(2)` (d) 4" Weba) If x is a positive real number, then x² is a positive real number. Therefore, if a² is positive, where a is a real number, then a is a positive real number. b) If x² ≠ 0, where x is a real number, then x ≠ 0. Let a be a real number with a² ≠ 0; then a ≠ 0.

Web0. if you use if x ,it means it has to evaluate x for its truth value.But when you use x ==True or x is True .It means checking whether type (x)==bool and whether x is True. attention : x is True is no equal to bool (x)==True. when you use x is True , you are checking the id of x and True. Share.
Webg(x) = sqrt(x) is not defined for all real numbers because if you take the square root of a negative number you get what mathematicians call an imaginary number. This is because a negative times a negative is always a positive and a positive times a positive is always a positive, meaning that you cannot have a real number times itself equal a negative. curtsy animationWeb12 jul. 2024 · Since the zeros of \(x^{2} -x+1\) are nonreal, we call \(x^{2} -x+1\) an irreducible quadratic meaning it is impossible to break it down any further using real numbers.
