3xbsmiddle" class="latex-formula">

Answer 1

The solution to the quadratic equation 3x² + 8x - 10 by using the quadratic formula is x = 0.927 or -3.594

Solving quadratic equations.

Quadratic equations are algebraic expressions that are represented in the power of the second degree. They usually take the form ax² + bx + c

From the given information, we are to solve the quadratic equation:

• 3x² + 8x - 10

Using the quadratic formula:

$\mathbf{=\dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}}$

where:

• a = 3
• b = + 8
• c = - 10

$\mathbf{= \dfrac{-(8)) \pm \sqrt{(8)^2 - 4(3 \times (-10))}}{2(3)}}$

$\mathbf{= \dfrac{-(8)) \pm \sqrt{64 -4 (-30)}}{6}}$

$\mathbf{= \dfrac{-(8)) \pm \sqrt{64+120}}{6}}$

x = 0.927 or -3.594
