Step-by-step explanation:
From the quadratic equation,
X = -b ±√b² - 4ac
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
2a
From the given equation, -3x² - x - 3 = 0
where a = -3, b = -1, c = -3
Now substitute for the values in the formula above
x = -(-1) ± √(-1)² - 4(-3)(-3)
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
2(-3)
x = 1 ± √ 1 - 36
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
-6
x = 1 ± √ -35
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
-6
x = -1 ± <em>i√35 this is because it has a negative root.</em>

Wish I could help<span>What are the measures of the angles located at positions a, b, & c? Note: the figure is symmetrical on the vertical through angle b. <span>The large triangle is an isosceles triangle. The two angles on the base are equal.<span>Angle a = 35° </span></span><span><span>We now know two angles in the largest triangle. The third angle, angle b must add to these to make 180°. </span><span>35° + 35° + b = 180°b = 180° - 70°b = 110° </span></span><span><span>We now know two angles in a quadrilateral. The two unknown angles, including angle c are equal. All four angles add up to 360°. </span><span>2c + 110° + 120° = 360°2c = 360° - 230°2c = 130°c = 65°
