Chapter 10: Q 10.63 (page 1188)

Solve the equation using quadratic formula.

4a2-3a+8=0

Short Answer

Expert verified

No real solutions.

The discriminant is less than zero or negative, the quadratic equation cannot have real solutions.

Step by step solution

01

 Given Information.   

The given equation is4a2-3a+8=0.

02

Write the quadratic equation in standard form and identify a,b,c.

The quadratic equation is in standard form.

So,

a=4,b=-3,c=8.

03

Substitute the values in quadratic formula.   

a=-b卤b2-4ac2aa=-(-3)卤(-3)2-4(4)(8)2(4)a=3卤9-1288a=3卤-1198

Since -119is not a real number, or we can say that the discriminant is less than zero.

The equation has no real solutions.
