Solve the equation below.<br> 5x^2 − 7x + 8 = 2
zavuch27 [327]

Answer:

\frac{7- \sqrt{71}i }{10}

\frac{7+ \sqrt{71}i }{10}

Step-by-step explanation:

5x^{2} - 7x + 6= 0

By quadratic formula,

Given in this question a = 5,

                                   b = -7

                                    c = 6

x can be

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

\frac{-b - \sqrt{b^{2} - 4ac } }{2a}

Putting these values in the formula we get,

x1 = \frac{7+ \sqrt{49 - 120} }{10}

x2 = \frac{7- \sqrt{49 - 120} }{10}

Explain why triangle pqs is isosceles
barxatty [35]

Answer    

By using the exterior angle property

The measure of exterior angle is equal to the sum of two opposite interior angles.  

In ∠QSR is exterior angle.

∠SPQ and ∠SQP are the opposite  interior angle of the exterior angle ∠QSR .

Thus

∠QSR  =  ∠SPQ + ∠SQP

As given in the diagram

∠QSR  =  2x  , ∠SQP = x

Put in the above

2x = x + ∠SQP

∠SQP = 2x - x

∠SQP = x

Thus

∠SPQ =  ∠SQP = x

By using the property

if two angles are equal in a triangle than their opposite sides are also equal .

Thus

PS = SQ

Two sides of triangle are equal .

therefore Δ PQS is a isosceles triangle .
