3x^2+4x<= 4

Solution

3 x^{2} + 4 x \leq 4

Solution

- 2 \leq x \leq \frac{2}{3}

+2

Interval Notation

[- 2, \frac{2}{3}]

Decimal Notation

- 2 \leq x \leq 0.66666 \dots

Solution steps

3 x^{2} + 4 x \leq 4

Rewrite in standard form

3 x^{2} + 4 x - 4 \leq 0

Factor

3 x^{2} + 4 x - 4 : (3 x - 2) (x + 2)

(3 x - 2) (x + 2) \leq 0

Identify the intervals

- 2 \leq x \leq \frac{2}{3}

Popular Examples

-4/3-13/4 (-10/3 a+2)=-62

- \frac{4}{3} - \frac{13}{4} (- \frac{10}{3} a + 2) = - 62

a^{2} + 5 a - 24 = 0

- 4 x + 9 = x - 1

simplify ((\frac{3x^2)/(20)*4y)}{((6xy)/(25))}simplify

\frac{( \frac{3 x ^{2}}{20} \cdot 4 y )}{( \frac{6 x y}{25} )}

6 - 54 w = 34 w - 10
