Question

plz and this I will give you 50pts only5 and 6 no​

Answer 1

Answer:

I hope it is right answer so plz mark me as brainliests and give thanks.

Step-by-step explanation:

5) => y^2-4y+3

=> y^2 +(-3-1)y+3

=> y^2-3y-y+3

=> y(y-3) -1(y-3)

=> (y-1) (y-3)

6) => x^2-21x+108

=> x^2+(-12-9)x+108

=> x^2-12x-9x+108

=> x(x-12) -9(x-12

=> (x-9) (x-12).

Answer 2

Answer:

1.

${x}^{2} + {11x} + 30$

$= {x}^{2} + 5x + 6x + 30$

$x(x + 5) + 6(x + 5)$

$(x + 6)(x + 5)$

${x}^{2} + 18x + 32$

${x}^{2} + 16x + 2x + 32$

$x(x + 16) + 2(x + 16)$

$(x + 2) (x + 16)$

${x}^{2} + 7x - 18$

${x}^{2} + 9x - 2x - 18$

$x(x + 9) - 2(x + 9)$

$(x + 9)(x - 2)$

${x}^{2} + 5x - 6$

${x}^{2} + 6x - 1x - 6$

$(x + 6) - 1(x + 6)$

$(x - 1)(x + 6)$

${y}^{2} - 4y + 3$

${y}^{2} - y - 3y + 3$

$y(y - 1) - 3(y - 1)$

$(y - 1)(y - 3)$

${x}^{2} - 21 x + 108$

${x}^{2} - 12x - 8x + 108$

$x(x - 12) - 8(x - 12)$

$(x - 8)(x - 12)$

here is your answer. hope it help you. please follow me and mark my answer as brainliests.
