MODEL ANSWER

(a)

Factorize:

x2−7x+12=0x^2-7x+12=0x2−7x+12=0 $$(x-3)(x-4)=0$$

Therefore,

x=3 or x=4\boxed{x=3 \text{ or } x=4}x=3 or x=4​

(b)

Given

$$2x+y=11$$ $$x-y=1$$

Add both equations:

$$3x=12$$ $$x=4$$

Substitute into

$$x-y=1$$ $$4-y=1$$ $$y=3$$

Answer

x=4,  y=3\boxed{x=4,\;y=3}x=4,y=3​

QUESTION 2

(a) Differentiate

y=5×4−3×2+7y=5x^4-3x^2+7y=5x4−3x2+7

(b) Find the gradient when

$$x=2$$

(a) Find the determinant.

(b) Find the inverse of A.

MODEL ANSWER

Determinant

$$=(2)(3)-(1)(5)$$ $$=6-5$$ 1\boxed{1}1​

Inverse

Since

$$|A|=1$$ A−1=(3−1−52)A^{-1} = \begin{pmatrix} 3&-1\\ -5&2 \end{pmatrix}A−1=(3−5​−12​)
