Hissa 2: Mukhtasar sawal (3)

Sawal 1. x² − 7x + 10 = 0 hal karein.

Namoona jawab dekhein

Factors: (x − 2)(x − 5) = 0, is liye x = 2 ya x = 5.

Sawal 2. Base 10 aur height 6 wale triangle ka area nikalein.

Namoona jawab dekhein

Area = ½ × base × height = ½ × 10 × 6 = 30 square units.

Sawal 3. Pythagoras theorem likhein.

Namoona jawab dekhein

Right angle triangle mein hypotenuse ka square baqi do pehlon ke squares ke majmue ke barabar hota hai: c² = a² + b².
