Question

write the following equations in the form of ax²+bx+c=0
1.)x²-11= -4x​

Answer 1

x² + 4x - 11 = 0

Step-by-step explanation:

x² - 11 = -4x

=> x² - 11 + 4x = 0

=> x² + 4x - 11 = 0

It is in the standard form of quadratic equation (ax² + bx + c = 0), here

• a = 1
• b = 4
• c = -11

hope it helps.

Answer 2

solution given :x²-9=13

x²-9-13=0

x²-22=0

comparing with general form of quadratic equations :ax² + bx + c =0

here ,a=1,b=0,c=22

hence the value of a=1,b=0,c=-22

how this answer will help you...
