The minimum value for the equation 3x2 + 18x + 15 = 0 repesented by 3(x + 3)2 = 12.
What is a quadratic equation?
A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The minimum value for the quadratic equation 3x^2 + 18x + 15 = 0
x^2 + 6x + 5 = 0
x^2 + (5 + 1)x + 5
x^2 + 5x + x + 5
(x + 5)(x + 2)
A)3(x + 3)^2= 6
B)3(x + 9)^2 = 12
C)3(x + 3)^2 = 12
D)3(x + 9)^2 = 228
Thus, the minimum value 3(x + 3)2 = 12.
