Question

Find and correct the errors in the following mathematical statements.
1) 4(x - 5) = 4x – 5
2) x(3x + 2) = 3x² + 2
3) 2x + 3y = 5xy
4) x + 2x + 3x = 5x
5) 5y + 2y + y - 7y = 0
6) 3x + 2x = 5x²
7) (2x)² + 4(2x) + 7 = 2x² + 8x + 7
8) (2x)² + 5x = 4x + 5x = 9x
9) (3x + 2)² = 3x² + 6x + 4​

Answer 2

Answer:

i)4(x-5)=4x-20

ii)x(3x+2)=3x²+2x

iii)2x+3y=2x+3y

iv)x+2x+3x=6x

v)5y+2y+y-7y=y

vi)3x+2x=5x

vii)(2x)²+4(2x)+7=4x²+8x+7

viii)(2x)²+5x=4x²+5x

ix) (3x+2)²=(3x)²+2×3x×2+(2)²=9x²+12x+4

hope this helps!
