. Solve: - 5x² + 5 = - 2x The solution contains a reduced fraction another reduced fraction with a radical numerator. What is this fraction with a radical numerator?
a

Step-by-step explanation:

Using the quadric formula:

Where,

Hence,

Consider the given quadratic equation that we have :

Multiplying both sides by -1 will yield ;

Write the above quadratic equation in the form of standard quadratic equation ax² + bx + c = 0 ,

Now , comparing this with the standard form of quadratic equation we will get a = 5 , b = -2 , c = -5 . So now , Discriminant (D) = (-2)² - 4 × 5 × -5 = 4 + 100 = 104

Now , by the quadratic formula ;

For any quadratic equation of the form ax² + bx + c , the Discriminant (D) is given by D = b² - 4ac , and the root of the quadratic equation is given by the quadratic formula as

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
