Question

Cn anyone help me with this...will mark as brainlest.... how 2 factorise them (sum and product )

Answer 1

⭐⭐Hello friend...Ur answer is here⤵⤵

⚫ x^2+14x+48

➡x^2+8x+6x+48

➡x(x+8)+6 (x+8)

➡(x+8)(x+6)

⚫y^2+2y-3

➡y^2-3y+y-3

➡y (y-3)+1 (y-3)

➡(y-3)(y+1)

⚫x^2-11x-42

➡x^-14x+3x-42

➡x (x-14)+3 (x-14)

➡(x-14)(x+3)

⚫x^2+12x-45

➡x^2+15x-3x-45

➡x (x+15)-3 (x+15)

➡(x+15)(x-3)

⚫4y^2-4y+1

➡4y^2-2y-2y+1

➡2y (2y-1)-1 (2y-1)

➡(2y-1)(2y-1) Or (2y-1)^2

I hope it is helpful to you☺

Answer 2

HEYA...

HERE IS YOUR ANSWER....


1] x^2 + 14x + 48

= x^2 + 8x + 6x + 48

= x[x+8] + 6[x+8]

= [x+6] [x+8]




2] y^2 + 2y - 3

= y^2 -y + 3y - 3

= y[y-1] + 3[y-1]

= [y-1] [y+3]




3] x^2 - 11x- 42

= x^2 + 3x - 14x - 42

= x[x+3] -14[x+3]

= [x+3] [x- 14]




4] x^2 + 12x - 45

= x^2 +15x -3x - 45

= x[x+15] -3[x+15]

= [x+15] [x-3]




5] 4y^2 - 4y +1

= 4y^2 - 2y -2y + 1

= 2y [2y - 1] - 1 [2y - 1]

= [2y-1] [2y-1]
