Answer 1

Answer:

Step-by-step explanation:

z^2 + 11z + 18

p*q=18

p+q=11

p=9;q=2

z^2 +9z + 2z + 18

z(z+9)+2(z+9)

(z+9)(z+2)

x^2 - 13x - 30

p*q=(-30)

p+q=(-13)

p=(-15);q=2

x^2 - 15x +2x - 30

x(x-15)+2(x-15)

(x-15)(x+2)

$\large\red {{z}^{2} + 11z + 18}$

${z}^{2} + 9z + 2z + 18$

$z(z + 9) + 2(z + 9)$

$(z + 9)(z + 2)$

$\large\red {{x}^{2} - 13x - 30}$

${x}^{2} + 2x - 15x - 30$

$x(x + 2) - 15(x + 2)$

$(x + 2)(x - 15)$

• What is a Term?
• It is something which is to be added or subtracted (subtracting is adding a negative number).

• What is a Factor?
• It is something that is to be multiplied.

• Splitting the middle term is a method for factoring quadratic equations. By the end of this section we'll know how to write quadratics in factored form.
