Question

solve the quadratic equation by factorisation( 1) 4x2-16= 0 (2) x2-2x+1=0 (3) 2x2-8x=0

Answer 1

Answer:

1. x=+04 or -04
2. x=01
3. x=00 or 08

Answer 2

Answer:

Step-by-step explanation:Answer:

X=130°,y=30°

Step-by-step explanation:

As l || m || n

Then angle 1=50°

Therefore angle 1 is equal to angle 2 = 50° (co-interior angles)

Then why linear pair

Angle x + angle 2 =180degree

x+50°=180°

x=180°-50°

x=130°

2. Angle y is equal to angle 3 equals to 30 degree (co -interior angles)
