[drowsy walrus]

can someone help me with question 4 please

[heady crow]

m is the same as m/1

so make the denominator the same by multiplying by x^2+1

then expand

so m(x^2-1)+nx+p = 2x^2+4x+5

[wild elm]

factorise the numerator and denominator

[heady crow]

mx^2+nx-m+p=2x^2+4x+5

[drowsy walrus]

thank you!

[heady crow]

what did you get as the answer?

[drowsy walrus]

n=4 m=2 p=7

[heady crow]

yup
