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.

3x2= 6 6-(4x-2)= 6--8= 6+8 = 14 14+7 = 21

x=-.25.

3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7

3x2 + 2x - 21 = (3x - 7) (x + 3)

3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7

3x2 + 2x - 21 = (3x - 7) (x + 3)

-3x2 + 22x = 0 You start by dividing both sides by x: ∴ -3x + 22 = 0 Then rearrange to solve for x: ∴3x = 22 ∴ x = 7 + 1/3

== == Suppose f(x) = x3 + 3x2 - 2x + 7 divisor is x + 1 = x - (-1); so rem = f(-1) = 11
