3x2 plus 7 equals 31?
no...no not quite, its 13, Here:3x2+7=x 3 times 2 equals 66+7=x 6 plus 7 equals 1313=x 13 equals xThere's yours answer, wasnt quite sure if it was a serious question or not but there ya go.
What is 3x2-4x plus 7 when x equals -2?
3x2= 6 6-(4x-2)= 6--8= 6+8 = 14 14+7 = 21
Solve 3x to the 2nd power equals 21 what are the solutions x equals and what is the x intercept?
3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7
How do you factor 3x2 plus 2x -21?
3x2 + 2x - 21 = (3x - 7) (x + 3)
When x3 plus 3x2-2x plus 7 is divided by x plus 1 the remainder is?
== == Suppose f(x) = x3 + 3x2 - 2x + 7 divisor is x + 1 = x - (-1); so rem = f(-1) = 11
What is the factor of 3x2 plus 22x plus 7 equals?
3x2 + 22x + 7 = 3x2 +21x + x + 7 = 3x(x + 7) + (x + 7) = (x + 7)(3x + 1)
