Question

If 2xsquare + 1 = 33, then the value of x will be.
​

Answer 1

Answer:

2x²+1=33

2x²=32

x²=16

x=4

Answer 2

Answer:

$\green{ x = ± \: 4}$

Step-by-step explanation:

${2x}^{2} + 1 = 33 \\ \\ \implies \: {2x}^{2} = 33 - 1 \\ \\ \implies \: {2x}^{2} = 32 \\ \\ \implies \: {x}^{2} = \frac{ \cancel{32}}{ \cancel2} \\ \\ \implies \: {x}^{2} = 16 \\ \\ \implies \: x = ±\sqrt{16} \\ \\ \implies \: x = ± \sqrt{ \underline \red{2 \times 2} \times \underline \pink{2 \times2 }} \\ \\ \implies \: x =± \: 2 \times 2 \\ \\ x = ± \: 4$

HOPE IT HELPS YOU !
