Question

28) a) The angles of a quadrilateral are (2x + 3)'. (x + 7)". (3x - 5)º
and (2x + 11)'. Find the measures of each angle of the
quadrilateral
b) Factorise
i) x2 - 14x + 49
ii) 144x2 - 44172
OR
4marks​

Answer 1

Answer:

X^2 - 7x - 7x +49 =0

X(x-7) - 7(x-7) = 0

(x-7) (x-7)=0

X-7=0 or x-7=0

X=7 or x=7
