4. Solve the equation using the quadratic formula.

Vikentia [17]

Answer:

A. x = -2, x = 1.25

Step-by-step explanation:

Use the quadratic formula

x = $\frac{-b+\sqrt{b^{2}-4ac } }{2a}$

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

4x² + 3x - 10 = 0

a = 4

b = 3

c = - 10

x = $\frac{-3+\sqrt{3^{2}-4x4(-10) } }{2x4}$

Simplify

Evaluate the exponent

x = $\frac{-3+\sqrt{9-4x4(-10)} }{2x4}$

Multiply the numbers

x = $\frac{-3+\sqrt{9+160} }{2x4}$

Add the numbers

x = $\frac{-3+\sqrt{169} }{2x4}$

Evaluate the square root

x = $\frac{-3+13}{2x4}$

Multiply the numbers

x = $\frac{-3+13}{8}$

Separate the equations

To solve for the unknown variable, separate into two equations: one with a plus and the other with a minus.

x = $\frac{-3+13}{8}$

x = $\frac{-3-13}{8}$

Solve

Rearrange and isolate the variable to find each solution

x = - 2

x = 1.25
