Question
Solve equation using factorisation method:$(2x - 3)^2 = 49$
✓
Answer
$(2x - 3)^2 = 49$ Taking square root on both sides
$2x - 3 = ± 7$
When $2x - 3 = 7 \Rightarrow 2x = 10 \Rightarrow x = 5$
and, when $2x - 3 = -7 \Rightarrow 2x = -4 \Rightarrow x = -2$
$2x - 3 = ± 7$
When $2x - 3 = 7 \Rightarrow 2x = 10 \Rightarrow x = 5$
and, when $2x - 3 = -7 \Rightarrow 2x = -4 \Rightarrow x = -2$
