Question 1 Report

Find the range of values of x for which 2x $^{2}$ + 7x - 15 ≥ 0.

x ≤ -5 or x ≥

\frac{3}{2}

x ≥ -5 or x ≤

\frac{3}{2}

-5 ≤ x ≤

\frac{3}{5}

\frac{3}{5}

≤ x ≤ -5

Answer Details

2x $^{2}$ + 7x - 15 ≥ 0

2x $^{2}$ -3x + 10x - 15 ≥ 0
x(2x - 3) + 5(2x - 3) ≥ 0
(x+5)(2x-3) ≥ 0
the points on x-axis where the graph ≥ 0

x ≤ -5 or x ≥ $\frac{3}{2}$

Find the range of values of x for which 2x2 2 + 7x - 15 ≥ 0.
