Q.2 Solve each of the following equations.
a) x(x-3)=5x+1
b) (x+2)(x-5)=4x
c) x(x-4)=2(x+7)

Answer 1

Answer:

Q.2 Multiply inside all the brackets.

Step-by-step explanation:

c. x^2-4x=2x+14

x^2-4x-2x-14=0

x^2-6x-14=0

a. = x^2-3x=5x+1

x^2-3x-5x-1=0

x^2-8x-1=0

b. x(x-5) 2(x-5)=4x

x^2-5x+2x-10=4x

x^2-5x+2x-10-4x=0

x^2-7x-10=0..
