#1

  • 10m²+m-3
  • 10m²-5m+6m-3
  • 5m(2m-1)+3(2m-1)
  • (5m+3)(2m-1)

#2

  • 4x²-20x+25
  • 4x²-10x-10x+25
  • 2x(2x-5)-5(2x-5)
  • (2x-5)(2z-5)

#3

  • 6n²+26n-20
  • 6n²+30n-4n-20
  • 6n(n+5)-4(n+5)
  • (6n-4)(n+5)

Answer:

d). (2m-1)(5m+3)

e). (2x-5)(2x-5)

f). (6n-4)(n+5)

Step-by-step explanation:

Solving by factorisation...

d). 10²+m-3

=> 10m²+6m-5m-3

=> 2m(5m+3)-1(5m+3)

=> (2m-1)(5m+3)

e). 4x²-20x+25

=> 4x²-10x-10x+25

=> 2x(2x-5) -5(2x-5)

=> (2x-5)(2x-5)

f). 6n²-20+26n

=> 6n²+26n-20

=> 6n²+30n-4n-20

=> 6n(n+5)-4(n+5)

=> (6n-4)(n+5)
